Question

When brakes are applied to a bus, the retardation
roduced is 25 cm s2 and the bus takes 20 s to
on Calculate : (i) the initial velocity of bus, and
Gii) the distance travelled by bus during this time.
​

Answer 1

a=v-u/t

25=0-u/20

-u=500cm/s

2as=v^2-u^2

2×25×s=250000

s=250000/50

= 5000m
