Question

A velocity of an object increases at constant rate from 20 metre per seconds to

50 metre per second in 5 second find the acceleration

Answer 1

Answer: 6m/s²

Explanation:

We know that a= v-u/t

we have

u (initial velocity)= 20m/s

v (final velocity)= 50m/s

t (time)= 5s

a= 50-20/5 m/s²

 = 30/5 m/s²

 =6m/s²

Answer 2

Answer:

Explanation:

V = 20 m|s

D = 50 m

T= 5 sec

Acceleration = v+u÷t

= 20+50÷5

= 70÷5

= 14 metre per second square
