Question

a body starts from rest and accelerators with 5m/s find the velocity by a body in three sec​

Answer 1

Answer:

15 m/s¯¹ is your answer friend

Explanation:

u = 0m/s¯¹

a = 5m/s¯²

t = 3s

v =?

v = u+at

v = 0+5(3)

v = 15m/s¯¹

Answer 2

Answer:

v= 15 m/s

Explanation:

Initial Velocity, u=0 as the body is at rest

acceleration, a=5m/s²

time, t=3s

using a=v-u/t

putting values

5=v-0/3

5×3=v

v= 15 m/s
