Question

the initial velocity of a particle is 10m/s and it is moving with uniform acceleration if its velocity is 50 m/s after 4 seconds then its displacement is

Answer 1

Answer:

120 m

Explanation:

Since the acceleration is uniform, let us apply the kinematic equations.

v = u + at

50 = 10 + 4a

40 = 4a

a = 10 m/x²

s = ut + at²/2

s = 10×4 + 10×16/2

s = 40 + 80

s = 120 m
