Question

A particle is moving with uniform acceleration 10 metre per second square .If it starts with velocity 2 m/s. Its velocity after 5 sec.is

Answer 1

Answer:

i

=10 m/s and v

f

=20 m/s

Acceleration of the body =

5

20−10

m/s

2

a=2 m/s

2

Velocity of the body at t=−3 sec

v=u+at

v=10−2×3

v=4 m/s

Please understand from this example
