The number of revolution made by a fly wheel change from 300rpm to1500rpm in 10s.Calculate angular acceleration assuming it to be uniform .Also calculate the number of revolution made during the time?

Answer 1

5 rps to 25 rps is 20 rps in 10 s

2 rps/s = 4π rad/s^2

average rpm is 900 or 15 rps

so 150 rev
