Question

A bus moving with a velocity of 60km/h is brought to rest in 20 secs . by applying brakes . find its acceleration.

Answer 1

u = 60 km/h = 50/3 m/s
t = 20 sec
v =0 m/s
a = (u-v)/t
 = (50/3)/20
= 5/6 m/s^2 = 0.83 m/s^2

Answer 2

Answer:-

u = 60 km/h = 50/3 m/s

t = 20 sec

v =0 m/s

a = (u-v)/t

= (50/3)/20

= 5/6 m/s^2 = 0.83 m/s^2
