:00:08. > :00:11.It's Tuesday morning, you're live with Newsround. I'm Leah with
:00:12. > :00:15.today's top stories, including: We find out what it takes to become a
:00:16. > :00:18.British bobsleigh driver. And: I'm Laura Trott. And I'm Jason Kenny,
:00:19. > :00:20.and we're here to answer your questions.
:00:21. > :00:24.But first, it's deadline day for Ukraine's new leaders. Former
:00:25. > :00:27.President, Viktor Yanukovych, was removed from power just days ago
:00:28. > :00:34.after huge anti-government protests and violence. Now the new leaders
:00:35. > :00:37.have until the end of the day to form a new, united government.
:00:38. > :00:40.Meanwhile British investigators are in the country helping to find out
:00:41. > :00:50.who told police to shoot at protestors last week. Dozens of
:00:51. > :00:54.people were killed in the clashes. Head to the website for more info on
:00:55. > :00:59.the story, including the report on the week's events, and a picture
:01:00. > :01:04.gallery telling you how the protests came about. Team GB's athletes have
:01:05. > :01:08.arrived home, bringing with them the four medals that will bring them
:01:09. > :01:11.more funding for winter sports. The men's curlers were first to appear
:01:12. > :01:14.with their silver medals. Lizzie Yarnold showed off her gold too
:01:15. > :01:18.fresh from carrying the union flag at the Games' closing ceremony. This
:01:19. > :01:21.morning, Britain's bobsleigh stars have been out and about talking to
:01:22. > :01:26.reporters, and it turns out if you're a good sprinter, you could be
:01:27. > :01:33.good at bobsleigh too. It's not too different. We came to add some extra
:01:34. > :01:38.speed to give it a magic touch, and I think we've done it. If you are a
:01:39. > :01:43.kid watching the Winter Olympics, how do you get involved? Go on the
:01:44. > :01:46.British bobsleigh website, and we have a futures programme where
:01:47. > :01:50.youngsters can try the sport out. There's a variety of ways to get
:01:51. > :01:54.involved, and hopefully the younger generation have been inspired by our
:01:55. > :01:56.performance. From one set of Olympic heroes to another. The World Track
:01:57. > :02:00.Championships begin tomorrow with Laura Trott and Jason Kenny aiming
:02:01. > :02:03.to defend the titles they won last year. They're two of Britain's
:02:04. > :02:07.biggest and best cycling stars, but before they headed off to Colombia
:02:08. > :02:10.to take part, they found the time to answer some of your questions. Great
:02:11. > :02:14.start by Laura Trott. Straight out of the gate.
:02:15. > :02:19.There he is, the Olympic sprint champion, he wins the gold medal,
:02:20. > :02:27.and he's won it in style with fantastic confidence.
:02:28. > :02:34.I chose to be a cyclist because I was good at it, to be honest. I like
:02:35. > :02:37.competing in anything and I love winning. I just like the winning
:02:38. > :02:48.feeling. Once you win one race, you want to win them all.
:02:49. > :02:53.There were four people fighting for three spots in the team pursuit, so
:02:54. > :02:57.we were competing against each other, so it was difficult. You have
:02:58. > :03:00.to train hard to get to the Olympics. We train super-hard.
:03:01. > :03:06.When I first started cycling I was eight years old and I did my first
:03:07. > :03:09.competition when I was ten, I think, a National Championships in
:03:10. > :03:13.Manchester. I had an older brother and I wanted to ride bikes, and I
:03:14. > :03:20.started riding on the track when I was 12. My first race was when I was
:03:21. > :03:24.12 as well. My main goal this year is to go to the world Championships
:03:25. > :03:27.and hopefully come away with a couple of medals, and then in the
:03:28. > :03:30.summer we have the Commonwealth Games. The Commonwealth Games in
:03:31. > :03:33.Glasgow should be good fun, so I'm looking forward to that.
:03:34. > :03:39.My favourite moment in my career was winning two gold medals at the
:03:40. > :03:43.London Olympic Games. My favourite moment in my career is winning two
:03:44. > :03:47.gold medals at the London Olympic Games as well.
:03:48. > :03:53.There he is, he wins the gold medal, and he won it in style.
:03:54. > :03:58.Footy now and the FA says it will investigate claims that supporters
:03:59. > :04:01.threw coins at Wayne Rooney during United's 2-0 win at Crystal Palace
:04:02. > :04:05.at the weekend. United are in Greece tonight, where they face Olympiakos
:04:06. > :04:09.in the Champions League. Rooney, who won Europe's top prize with United
:04:10. > :04:15.back in 2008, wants them to go all the way again.
:04:16. > :04:23.We want to win, so the feeling you get when you actually win the trophy
:04:24. > :04:28.is incredible. There is no way would want to stop one. The to win every
:04:29. > :04:33.year, and that might be impossible, but if we can go to the final it
:04:34. > :04:36.would be great for us and it's an opportunity to win the trophy, so,
:04:37. > :04:40.hopefully we can do that. Last up, to the story of this incredibly cute
:04:41. > :04:43.panther cub's brave recovery. This tiny cat was finding his first weeks
:04:44. > :04:47.of life quite tough while living at a wildlife refuge in Florida and he
:04:48. > :04:51.nearly died. But luckily the cub was sent off to hospital and received
:04:52. > :04:54.special treatment to build him back up. He's now happy, healthy and
:04:55. > :05:00.enjoying his bottle of milk! That's all from me, Newsround's back this
:05:01. > :05:01.afternoon. Have a great day, whatever you're doing.
