Two objects of mass 1 kg and 0.5 kg are moving on linear path with velocity 4 ms^(-1) and 2 ms^(-1) in the same direction respectively collide with each other. After collision, velocity of first object is 3m s^(-1) in the same direction. Find out the velocity of the second object.

The weight of an object whose mas is 1 Kg is

A solid sphere has a radius of 2 cm and a mas of 0.05 kg. What is the relative density of the sphere ? (AS_(1))

Two blocks of masses 3 kg and 6kg rest on horizontal smooth surface. The 3 kg block is attached to a spring with a long constant k=900Nm^(-1) which is compressed 2m from beyond 1m from mean position. 3kg mass strikes the 6 kg mass and the two stick together.

1 kg m = 9.8 J

Two obhects.each of masss 1.5 kg are moving in the same straight line but in opposite directions.The velocity of each object is 2.5 m s^(-1) before the collision during which they stick together.What will be the velocity of the combined object after collision?

The external force necessary to produce acceleration 5 m s^(-2) in an object of mass 2 kg Is F_(1) , and that to produce acceleration 2 m s^(-2) in an object of mass 4 kg is F_(2) , then….hold. (F_(1)=F_(2).F_(1)gtF_(2).F_(1)ltF_(2))
