A student on an amusement park ride moves in circular path with a radius of 3.5 m once every 4.5 s. What is the tangential velocity of the student?

the tangential velocity of the student is 4.89 m/s.

Explanation:

Given;

the radius of the circular path, r = 3.5 m

duration of the motion, t = 4.5 s

let the student's tangential velocity = v

The tangential velocity of the student is calculated as follows;

Therefore, the tangential velocity of the student is 4.89 m/s.

prolly a beacuse the momentuem the car has increases while going down hill

the answer is b, have negligible mass
