A 5kg. mass is accelerated from rest to 60 m/s in 1 sec. what force acts on it:-

A 10 kg weight is accelerated from rest to 20 m/s in 1 sec. What force acts on it:

A 810 kg car accelerates from rest to 27 m/s in a distance of 120 m. What is the magnitude of the average net force acting on the car ?

A car of mass 1000 kg accelerates uniformly from rest to a velocity of 15 m/s in 5 sec. The average power of the engine during this period in watts is :

A block of mass 15kg is placed on a long trolley. The cofficient of fricition between the block and trolley is 0.18. The trolley accelerates from rest with 0.5m//s^(2) for 20s. then what is the friction force:-

When a force 1N acts on 1kg mass at rest for 1s, its final momentum is P. When 1N force acts on 1kg mass at rest through a distance 1m, its final momentum is P1. The ratio of P to P1 is
