ANSWER:
Solution 4PE
Step 1 of 5
The angular acceleration with which the player spins the basketball is . Here we need to calculate the ball’s final angular velocity
if it starts from rest and the given acceleration is for time
. Also, we need to comment on the result about the inconsistency.
Given data,
Angular acceleration,
Initial angular velocity, (as ball starts from zero)
Time interval,
To find,
Final angular velocity,
