Question

A particle starts with a velocity of 5 metre per second and moves with a uniform acceleration of 2.5 metre per second square distance travelled in 4s​

Answer 1

According to Newton's 2nd law of motion

Where s=distance ; u=previous velocity ; a=acceleration ; t=time

s=ut+½at²

u=0 because the body has just started moving

s=0+½×2.5m/s²×4s×4s

s=0+20m

s=20m
