Answer 1

Answer:

1. if any luggage tie on the roof of the bus and not tied with rope then it tends to move forward due to its inertia. in this situation it tends to fall from the bus . so it is advised to tie any luggage tie on the roof of the bus.

2. Acceleration

3. Given,

t= 10 min. = 10 × 60s= 600s

initial velocity of train = 0m/s

final velocity of train = 40km/h= 40×1000/3600 = 11.1m/s

Acceleration= v-u/t

= 11.1-0/600m/s

= 0.0185m/s^2
