Question

.Starting from rest from one end of a runway, a jet airliner acquires a speed of 90 m/s in 1 minute.
Express your idea about how much acceleration it attains and evaluate the distance travelled. Also, we
know that seat belts help to keep drivers and passengers safer when the vehicles stop suddenly during an
accident. Justify the statement based on your observations.

Answer 1

Summary-This is the basic problem from Motion. I have provided the step by step solution.

Acceleration of jet is 1.5 m/s2  and distance travelled is 2700m.

During motion in a vehicle,driver and passengers travels with the same speed as that of vehicle. During an accident,speed of car reduces suddenly, but speed of passengers doesn't so which might harm them.seat belt helps passengers and drivers to reduce the speed suddenly along with the vehicle by sticking to the vehicle's seat with the help of seat belt.
