Find the force required to stop a car of mass 100Kg with two passengers of
50 g each sitting inside,if it is moving at 60km/h speed and takes 5s to stop.
Dear Student
It is given that:
- Mass of car = 100 kg
- Two passengers with each of a mass of 50 g = 0.05 kg
- Initial velocity = 60 km/h = 60 (5/18) = 50/3 m/s
- Car takes 5 s to stop
Initial velocity u = 50/3 m/s
Final velocity v = 0
