Question

A wheel rolling on a horizontal surface with an angular speed of 2.5 rad/s gets on a ramp and rolls down the ramp with a constant angular acceleration of 2.0 rad/s2. If it takes 11.5 us to reach the bottom of the ramp, what is the final angular speed of the wheel at the bottom

Answer 1

Answer:

the final angular speed of the wheel at the bottom is 25.5 rad/s

Explanation:

The computation of the final angular speed of the wheel at the bottom is as follows:

As we know that

$W_f = W_{in} + \alpha t\\\\= 2.5 + (2 \times 11.5)\\\\= 2.5 + 23\\\\= 25.5 rad/s$

Hence, the final angular speed of the wheel at the bottom is 25.5 rad/s

We simply applied the above formula so that the final angular speed could come
