Question

In the uniform acceleration velocity of the particle at any point ‘p’ is 20 m/sec. After

covering 25m, its velocity becomes 30 m/sec. What will be the velocity 15 m before the

point ‘p’ is.​

Answer 2

Explanation:

v

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
