Question

When brakes are applied to a bus, the retardation produced is 25 cm -square and the bus takes 20second to stop. Calculate its initial velocity of bus and distance travelled by bus ​

Answer 1

Answer:

5m/s^-1

Explanation:

Retardation is 25cm/s^2, therefore,

Acceleration, a=−0.25m/s^2

t=20s,v=0

Putting the values in v=u+at

0=u+(−0.25)(20)

u=5m/s
