Question

A particle moves in a circular path of radius 5 m with constant speed 5 m/s.find the magnitude of its average acceleration when it completes half revolution​

Answer 1

Answer:

2.5π²

Explanation:

time = distance/speed

time = 2π*5/5 = 2π

velocity = displacement/ time

velocity = 10/2π = 5/π

acceleration = velocity /time

acceleration = 5/π*2π = 5/2π² = 2.5π²
