A jeep, scooter, a car and a truck are moving on a road at the same speed of 70 m/s under identical conditions. All these vehicles are hit from behind with the same force and they keep moving forward in the same direction. The maximum acceleration will be produced in the:

• A. Scooter
• B. Jeep
• C. Truck
• D. Car

Answer 1

Answer: (A)

Scooter

Acceleration of the vehicle $a=\frac{F}{m}$ $⟹a\propto \frac{1}{m}$ $(\because F=constant)$

As the scooter is the lightest vehicle, thus scooter has the maximum acceleration.
