Question

1) You are standing on a merry go round with a radius of 1.2 m. Your friend accelerates the merry go round from rest at a constant angular acceleration of 1.5 radians/s^2

A) After 4 seconds the merry go round abruptly stops and you fly off. Will your velocity be linear or angular? What direction is your velocity

My guess is that your direction is linear, but I am not sure the direction of the velocity.

B) What will be the magnitude of your velocity?

Answer 1

A)

Velocity will be linear.

Direction is tangential to wheel

B)

V = r a t = 1.2 x 1.5 x 4 = 7.2 m/s

Comment in case any doubt please rate my answer ....
