A child riding a merry-go-round is sitting on a horse onto a stationary pole 10m from the center of the merry-go-round. The ride starts from rest and with constant angular accleration obtains an angular velocity of 2 rad/s in 10 seconds. It then continues at 2 rad/s for 15 seconds and then brakes and comes to a stop with a deceleration of -0.1 rad/s^2.
1. Graph the angular velocity from start to stop
2. At 20 seconds, what is the centripital accleration of the child on the merry go round?
3. At 30 seconds, what is the tangential accelration of the child on the merry go round?
4. At 5 seconds, what is the magnitude of the total accel. of the child on the merry go round
5. What is the total angle, theta, that the merry go round travels during the first 15 seconds?
thank you in advance!
