Question

A body is moving vertically upwards. Its velocity changes at a constant rate from

50 m s-1

to 20 m s-1

in 3 s. What is its acceleration?​

Answer 1

Explanation:

a=v/t

a=(50-20)/3

a=10 m per sec^2

Answer 2

Answer:

here intial velocity=50ms-1,final velocity=20ms-1,t

time=3s.

A=v-u/t

a=20-50/3

a=-30/3

a=-10ms-2.

hence the accn of body is -10ms-2.
