Two bodies of different masses `m_(1) and m_(2)` are falling from the same height. If resistance offered by the air be the same for both the bodies, then will they reach the earth simultaneously? Assume `m_(1) gt m_(2)`.

Two bodies of different masses m_a and m_b are dropped from the heights a and b respectively.What is the ratio of time taken by the two bodies to drop through these distances?

Two bodies of masses m_(1) and m_(2) are separated by a distance R. The distance of the centre of mass of the bodies from the mass m_(1) is

Two balls of different masses have the same volume. If the air resistance on both the balls are the same, prove that, when dropped from the same height, the heavier ball reaches the ground earlier.

Two masses m_(1) and m_(2) are connected to the ends of string passing over a pulley. Find the tension and the acceleration associated.

A body of mass 0.03 kg , falling from a height of 20 m, penetrates 1.5 m into the soil. Find the average resistive force of the soil.

Two bodies having masses m_(1) and m_(2) are dropped from heights h_(1) and h_(2) respectively. They reach the ground after times t_(1) and t_(2) and strike the ground with velocities v_(1) and v_(2) respectively. Choose the correct relations from the following:
