Question

Starting from seest a scooter acquires a velocity of
36kmh in los and then brakes are applied it
takes 20s to stah calculate acceleration and
distance trevelled.​

Answer 1

Explanation:

Given:

u = 0

v = 36km/h = 36×5/18 = 10m/s

t = 20s

a = (v-u)/t

= (10-0)/20

= 0.5m/s²

v²-u² = 2as

10²-0² = 2×0.5×s

100=1s

s = 100m
