A particle starts moving along a straight line path with velocity `10m//s`. After `5s` the distance of the particle from the starting point is `50m`. Which of the following statements about the nature of motion of the particle are correct?

Options

A. The body may be speeding up with constant positive acceleration.
B. The motion may be moving with constant velocity.
C. The body may have constant negative acceleration.
D. The motion may be first accelerated and then retarded.

Answer

B, C, D

Explanation

b,c,d. `u = 10ms^(-1), t = 5s, S = 50 m`
`V_(av.) = 50/5 = 10ms^(-1)`
The motion may be with constant
velocity.
T he body may be first accelerated and then retarded.
