Question

The change in angular velocity of the tire of the bicycle is 5 rad's during the time period of 1.25 s. Calculate the value of the angular acceleration of the tire of the bicycle. (A) 1.5 rad's (B) 2 rad's (C) 0,4 rad's (D) 4 rad's​

Answer 1

Answer:

answer is d

4 rad's

Explanation:

ANSWER IS (D)

Answer 2

Answer:

Wheel speed = angular velocity × radious.

= 10 × 0.4

= 4 m/s.

So the speed of cycle is 4 m/s.
