You are told that a basketball player spins the ball on his finger with an angular acceleration of 118 rad sa 50% part (a) what is the ball's final angular speed in radians per second, if the ball starts from rest and the acceleration lasts 3.4 s?

ω = 401.2 rad/sec

Explanation:

we know that in a circular motion

ω= final angular velocity

ω0=  initial angular velocity

α=  angular aceleration

t= time

Given ω0= 0, and t=3.4 sec

to find final angular velocity that is ω

⇒ω = 401.2 rad/sec

where is the photo and the answer choices?
