Two objects of massses `m_(1)` and `m_(2)` having the same size are dropped

Two objects of masses m_(1) and m_(2) having the same size are dropped simultaneously from heights h_(1) and h_(2) respectively. Find out the ratio of time they would take in reaching the ground. Will this ratio remain the same if (i) one of the objects is hollow and the other one is solid and (ii) both of them are hollow, size remaining the same in each case. give reason.

Two bodies of masses m_(1) and m_(2) have same kinetic energy. The ratio of their momentum is

Two objects of masses 100g and 200g are moving along the same line in the same line in the same direction with velocities of 2m//s and 1m//s , respectively. They collide and after the collison, the first object moves at a velocity of 1.67 m//s in the same direction. Determine the velocity of the second object.

Two bodies of masses m_1 and m_2 have the same linear momentum. What is the ratio of their kinetic energies?

Two objects A and B of masses m_(A) and m_(B) are attached by strings as shown in fig. If they are given upward acceleration then the rato of tension T_(1) : T_(2) is-

Two particles of masses m_(1) and m_(2) are moving in concentric circle of radii r_(1) and r_(2) such that their period are same. Then the ratio of their centripetal acceleration is

Two bodies of masses m_(1) and m_(2) have equal KE . Their momenta is in the ratio

Two stones of mass m_1 and m_2 (such that m_1 gt m_2 ) are dropped Deltat time apart from the same height towards the ground. At a later time t the difference in their speed is DeltaV and their mutual separation is DeltaS . While both stones are in flight

There different objective of masses m_(1) , m_(2) and m_(2) are allowed to fall from rest and from the same point O along three difference frictionless path .The speeds of three objects on reaching the ground will be
