Question

A body is moving in a circle with a speed of 1 m/s. This
speed increases at a constant rate of 2 m/s every second.
Assume that the radius of the circle described is 25 m. The
total acceleration of the body after 2 s is ?

Answer 1

Answer:

1rad/s

Explanation:

Given,

initial velocity, u = 1 m/s

acceleration,a = 2

time = 2 s

according to the law of motion, final velocity

v = u + at

=> v = 1 + (2) x (2)

=> v = 5 m/s

So, the final velocity of the body will be 5 m/s

radius of the circular path = 25 m

hence, angular acceleration can be given

    = 1 rad/s
