A projectile of mass ` 100 g` is fired with a velocity of ` 20 ms^(-1)` making an angle of ` 30^@` with the borizontal. As it rises to the highest point of its path its momentum changes by .

A particle of mass 100 g is fired with a velocity of 20 ms^(-1) making an angle of 30^(@) with horizontal. When it rises to the point of its highest point, find the change in its momentum.

A cannon ball is fired with a velocity of 200 ms^(-1) at an angle of 60^(@) with the horizontal. At the highest point of its flight it explodes into 3 equal fragments. One fragment is going vertically upwards with a velocity of 100 m//s and second going vertically downwards with a velocity of 100 ms^(-1) the third fragment will be moving with a velocity of

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))
