Question

A body is moving with a velocity of 15 m /s if the motion is uniform what will be the velocity after 10 m/s

Answer 1

Answer:

Explanation:

Given,

initial velocity ( u ) = 15 m/s

time ( t ) = 10s

final velocity ( v ) = ?

We need to find the Final velocity

We know that motion is uniform, so we can find the acceleration of the body

let u = 0 m/d ; v = 15 m/s ; t = 10s

a = v-u/t

  = 15/10

  = 1.5 m/s²

Now the velocity after 10s

v = u + at

v = 15 m/s + [ 1.5 m/s² ][ 10s ]

v = 15 m/s + 15 m/s

v = 30 m/s
