Question

A wheel is rotating with an angular velocity of 3 rad s^(-1). If the angular acceleration is 2 rad s^(-1) then calculate its angular velocity after 5 second.

Answer 1

Answer:

................... . .......

Answer 2

Answer:

angular velocity is 13rad/sec

Explanation:

GIVEN DATA:

initial angular velocity of wheel=3rad/s

angular acceleration of wheel=2rad/s

time taken by wheel=5seconds

TO FIND:

final angular velocity=?

SOLUTION:

as we know:

wf=wi+ a t

so put values:

wf=3 + 2*5

wf=13rad/sec
