Question

when a body move with velocity 10m per sec after 5 sec the speed of body becomes 15 m per sec find out the acceleration of the body...​

Answer 1

Explanation:

Initial speed (u) 10m/s

Final speed (v) 15m/s

Time (t) 5sec

by using the formula v=u+at

we get 15=10+5a

15-10 = 5a

5 = 5a

a = 1

Acceleration 1m/s²

Thanks

Answer 2

Answer:

1 m / sec²

Explanation:

Given :

Initial velocity ( u ) = 10 m / sec

Final velocity ( v ) = 15 m / sec

Time ( t ) = 5 sec

We have to find acceleration :

We have :

v = u + a t

15 = 10 + 5 a

5 a = 15 - 10

5 a = 5

a = 1 m / sec²

Hence we get acceleration of the body 1 m / sec² .
