Question

A body moving with uniform acceleration travels 84 m in 6s and travels 180m in next 5 s.find:(a) initial velocity (b) acceleration

Answer 1

a) Initial velocity = Initial displacement/time

u = 84 / 6

u = 14 m/s

b) a = v - u / t = 180 / 5 - u / t

= 36 - 14 / 6 + 5

= 22 / 11

= 2 m/s/s
