Question

the velocity of an object increases at a constant rate from 20 m/ sec to 50 m/ sec in 10 s .find the acceleration​

Answer 1

Answer:

The acceleration is 3m/s^2.

Explanation:

Initial velocity,u = 20m/sec

Final velocity,v = 50m/sec

Time, t = 10 sec

Acceleration,a = v-u/t = 50-20/10 = 30/10 = 3 m/ s^2.
