Question

A car moving with velocity 50m/s stops in 5
seconds, what is the value of acceleration?​

Answer 1

Answer:

-10 m/s

Explanation:

Here, v=0 m/s    u=50m/s        t= 5s

a = (v-u)/t

a= (0-50)/5

a= -10 m/s

Answer 2

Explanation:

acceleration =vf-vi/t

final velocity =Vf=0

initial velocity=Vi=50m/s

time =t=5sec

Solution:

a=0–50÷5

a=–5m/s²

Hope it help you
