Question

A particle moving with an initial velocity of 5metre per second is subjected to a uniform acceleration of 2.5metre per second square find the displacement in the next 4second

Answer 1

u = 5 m/s

a = 2.5 m/s^2

t = 4 s

s = u t + 1/2 a t^2

so, s = 5*4 + 1/2 * 2.5* 4^2

= 20 + 20

= 40 m is the displacement in next 4 seconds

Answer 2

Heya...

Kindly refer to above attachment...

Displacement in the next 4 second will be... 40 m..
