A force of 20 N acts on a body of mass 5kg at rest. What is the acceleration of the body ? What is its velocity after 5 seconds if the same force acts? After 5 seconds if the force ceases to act how will the body move?

A

`4m//s^2` , 20 m/s, uniform velocity

B

` 2m//s^2` , 15 m/s , uniform velocity

C

`2m//s^2` , 10 m/s , uniform velocity

D

`4m//s^2` , 20 m/s, uniform acceleration
