Question

8. A body starts from rest and picks up the velocity of 15 m/s in 3 s. Find its
acceleration
​

Answer 1

Answer:5 m/s²

Explanation:

INTIAL VELOCITY = 0; FINAL VELOCITY=15m/s

TIME= 3s

ACCELARATION= v-u/t

                           = 15-0/3

                            =5m/s²

Answer 2

Answer:

5m/s²

Explanation:

v=u+at

v=15m/s

t=3s

u=0 (since the is starting from rest)

substituting the values

15=0+a(3)

15=3a

15/3=a

5=a

a=5m/s²

therefore acceleration of the body is 5m/s².
