Question

A body moving from rest with uniform acceleration and travels 270 m in 3 seconds find the velocity of the body at 10 seconds after the start

Answer 1

First use the formula (s = ut + 1/2 at^2) to find the acceleration.
270 = 0(3) + 1/2(a)(3^2)
a= 60m/s^2

Use this value of a to calculate v using the formula:
v = u + at
v = 0 + (60)(10)
v = 600m/s
