Question

4. The velocity acquired by a body moving with uniform acceleration is 12m/s in 2s and 18m/s in 4s. Find the
initial velocity of the body and acceleration.​

Answer 1

v = u + at

12 = u + 2a

and

18 = u + 4a

Subtract first equation from second.

18 - 12 = u - u + 4a - 2a

6 = 2a

a = 3 m/s^2
