initial velocity, (u) = 0m/s
time taken to acquire velocity(t1) = 10 s
v1 = 36km/hr = 10m/s
therefore, initial acceleration = v1/t1 = 1m/s^2
when the scooter stards retarding the motion
initial velocity (v1) = 10m/s
final velocity (v2) = 0m/s
time taken to stop = 20s
therefore,
retardation produced (a') = -(-10/20) = 0.5m/s^2
total distance travelled =
distance during 10s + diastance during next
20 s
time taken to acquire velocity(t1) = 10 s
