Complete number 2 please!

1.) In a particular rear-end car collision the driver’s head rotates 45° back- ward before being stopped by the head- rest. What is the average angular velocity of the driver’s head if the duration of the collision was 0.1 s?

2.) A 20kg child is spinning on a carousel (radius =1.5m) and accelerates to a speed of 2 m/s.

What is the angular velocity of the carousel?

The child then jumps on

What is the force exerted by the child if he is hanging on the bar?
Now, the child moves closer inside of the carousel and is 0.5m from the center. What is the new force of the child hanging onto the bar? What is the new force if he is 0.7m from the center?
After 3 minutes, the carousel slowed down at about 30%. What is the total angular displacement of the carousel during the 3 minute time (in revolutions)?

Definition Definition Angle at which a point rotates around a specific axis or center in a given direction. Angular displacement is a vector quantity and has both magnitude and direction. The angle built by an object from its rest point to endpoint created by rotational motion is known as angular displacement. Angular displacement is denoted by θ, and the S.I. unit of angular displacement is radian or rad.
