A particle is moving along a circular along a circular path of radius 5 m with a uniform speed `5ms^(-1)`. What will be the average acceleration when the particle completes half revolution?

Options

A. The total distance travelled by the particle
B. The horizontal range of the particle
C. The maximum height risen by the particle
D. None of these

Answer

C

Explanation

In ground frame [A] it is simply a projectile motion. But in [B] frame horizontal component of the displacement is zero i.e. in this frame only vertical comp. appear which is responsible for the maximum height.
