Question

the velocity of a moving body changes at the constant rate from 50 M second 20 M per second in 3 seconds find acceleration

Answer 1

V = 20m / s

U = 50 m/s

T = 3 sec.

A = V - U /T

= 20 - 50 / 3

= -30 /3

= -10 m/s ^2 ans .

Answer 2

Given :- u = 50 m/s
v = 20m/s
t = 3seconds
To find :- acceleration
a = change in velocity / time taken
a = 50-20/3
a = 30/3
a = 10 m/s
