On an object of mass 1 kg moving along x-axis with constant speed 8 m/s, a constant force 2 N is applied in positive y-direction. Find its speed after 4 seconds.

A body of mass 2 kg is moving along x-direction with a velocity of 2 m//sec. If a force of 4 N is applied on it along y-direction for 1 sec, the final velocity of particle willbe-

A particle of mass m is moving with constant speed v on the line y=b in positive x-direction. Find its angular momentum about origin, when position coordinates of the particle are (a, b).

An object of mass 10kg moves at a constant speed of 10 ms^(-1) . A constant force, that acts for 4 sec on the object, gives it a speed of 2ms^(-1) in opposite direction. The force acting on the object is :

An object of mass 20 kg moves at a constant speed of 5ms^(-1) . A constant force, that acts for 2 sec on the object, gives it a speed of 3ms^(-1) in opposite direction. The force acting on the object is
