Question

A body moving with a velocity of 10m/s increases its velocity to 20m/s in 2s. Then the rate of change in velocity is​

Answer 1

Answer: it's oscillation

Explanation:

Answer 2

Explanation:

For time period answer is oscillation.

The rate of change in velocity is called acceleration

a = v- u/t

a= 20 - 10 /2

a= -10/2

a = -5 m/s^2

negative acceleration is called retardation

therefore the body undergoes retardation
