A particle of mas 70g, moving at `50cm//s`is acted upon by a variable force opposite to its direction of motion. The force F is shown as a function of time t.

A

Its speed will be `50 cm//s` after the force stops acting

B

Its direction of motion will reverse

C

Its average acceleration will be `1m//s^(2)` during the interval in which the force acts

D

Its average acceleration will be `10 m//s^(2)` during the interval in which the force acts.
