Two bodies of masses m and 4m are moving with equal kinetic energy. The ratio of their momenta is:
A body of mass 50 kg has a momentum of 250 kg·m/s. What is its kinetic energy?
A force F = (3x + 2) N acts on a particle moving along the x-axis. The work done by this force in moving the particle from x = 1 m to x = 4 m is:
A body of mass 3 kg is thrown vertically upwards with a velocity of 20 m/s. What is its potential energy at the maximum height? (g = 10 m/s²)
A body of mass 1 kg moves in a straight line with velocity v = 3t m/s, where t is in seconds. The work done by the net force during the first 2 seconds of motion is:
Two bodies of masses 1 kg and 4 kg have equal kinetic energies. The ratio of their momenta (p₁/p₂) is:
An object of mass 100 kg is kept at a height of 5 m above the ground. If it is dropped, what is its kinetic energy just before hitting the ground? (Take g = 10 m/s²)
A body of mass 2 kg is thrown upwards with a velocity of 30 m/s. Its kinetic energy at the moment of throwing is:
