Assertion : Two bodies of unequal masses m_1 and m_2 are dropped from the same height. If the resistance offered by air to the motion of both bodies is the same, the bodies will reach the earth at the same time. Reason : For equal air resistance, acceleration of fall of masses m_1 and m_2 will be different.

Two bodies have same mass and speed, then

Two bodies of different masses are dropped simultaneously from the top of a tower. If air resistance is proportional to the mass of the body then,

Two bodies of different masses are dropped from height of 16 m and 25 m respectively. The ratio of the times taken by them is

Two bodies of different masses m_(a) and m_(b) are dropped from two different heights a and b. The ratio of the time taken by the two to cover these distances are

A body is dropped from a certain height.

Two bodies of unequal mass are moving in the same direction with equal kinetic energy. The two bodies are brought to rest by applying retarding force of same magnitude. How would the distance moved by them before coming to rest compare ?

Two bodies of different masses m_(a) and m_(b) are dropped from two different heights, viz, a and b. The ratio of time taken by the two to drop through these distance is:

When two bodies of equal masses collide elastically then
