Question

A car moving with speed of 108 km/her and stops after applying brakes in 6 sec Find the acceleration​

Answer 1

Answer:

-5m/s^2

Explanation:

v=0(as the car's final velocity is zero)

u=108km/hr= 30m/s^2

t=6s

a=?

v=u+at

0=30+6a

-6a=30

a=-5m/s^2

as the body is stopping so acceleration is 5m/s^2
