Question

a body is moving with a velocity of 4m/s and with a uniform acceleration. it attains a speed of 20m/s after travelling a distance of 96n. find the acceleration.

Answer 1

We, know that ,
v^2 - u^2 = 2as.
=> 20 ^2 - 4^2 = 2× 96 × a
=> 400 - 16 = 192a
=> 384/192 = a
=> 2 = a

Therefore, the acceleration = 2m/s^2
