Question

The velocity of a moving body changes at a constant rate from 50m/s to 20m/s in 3sec. Find acceleration

Answer 1

a=(v-u)/t=20-50/3=-10m/s^2

Answer 2

HOLA!!

________

HERE YOUR ANSWER IS

Acceleration = change in velocity / time

GIVEN

Initial velocity (u) = 50m/s

Final Velocity (v) = 20m/s

time (t) = 3 sec

SOLUTION

Acceleration = (v-u)/t

= (20 -50)/3

= (-30) /3

Acceleration = -10m/s^2

____________

Here negative indicates that it's moving in opposite direction .

We can say it be decelerating or regarding.
