Question

An object starting from rest travel with an acceleration of 5 m/s^2what will be velocity from 3s

Answer 1

your ans is here

_________

given:-

object is starting from rest so

u=0

v=?

t=3

a=5

acceleration:- v-u/t

5=v-0/3

15=v-0

15m/sec=v

____________

u=initial velocity
v=final velocity

_________

Answer 2

hiii...

first of all ..
as we know that ..

v = final velocity
u = initial velocity

now ,

in this case body start from rest then the initial velocity is zero.

so , accelration = v- u/ t

given :- a = 5m/s^2 and t= 3s

so,

solution ,,

a = v- u/ t

=> 5 = v-0 / 3

=> v = 5 × 3

=> v = 15 m/s.
