Question

A bus decreases its speed
from 80 kilometer per hour to 60
kilometer per hour in s second
Find the acceleration of
the bus.​

Answer 1

Explanation:

★WE HAVE,,

•Initial speed of the bus,u = 80 km/h = 200/9 m/s

•Final speed of the bus,v = 60 km/h = 150/9 m/s

•Time taken by the bus,t = s sec

• Acceleration of the bus,a = ??

USING a = (v-u)/t ,,

WE GET,,

a = (150/9)-(200/9))/s

=> a = -50/9s m/s²
