A body of mass 2 kg is projected at 20 `ms^(-1)` at an angle `60^(@)`above the horizontal. Power due to the gravitational force at its highest point is

A body of mass 1kg is projected with velocity 50 ms^(-1) at an angle of 30^(@) with the horizontal. At the highest point of its path a force 10 N starts acting on body for 5s vertically upward besids gravitational force, what is horizontal range of the body (Take, g = 10 ms^(-2))

An object of mass 5 kg is projecte with a velocity of 20ms^(-1) at an angle of 60^(@) to the horizontal. At the highest point of its path , the projectile explodes and breaks up into two fragments of masses 1kg and 4 kg. The fragments separate horizontally after the explosion, which releases internal energy such that K.E. of the system at the highest point is doubled. Calculate the separation betweent the two fragments when they reach the ground.
