two copper balls having masses 5 gm and 10 gm collide with a target with the same velocity. If the total energy is used in heating the balls. Which ball will attain higher temperature?

Two metal balls having masses 50g and 100g collides with a target with same velocity. Then the ratio of their rise in temperature is

Two metal balls having masses 50g and 100g collides with a target with same velocity. Then the ratio of their rise in temperatures is

If two balls of same metal weighing 5 gm and 10 gm strike with a target with the same velocity. The heat energy so developed is used for raising their temperature alone, then the temperature will be higher

A ball moving with speed u collides with an identical ball at rest. The velocities of two balls after collision are (If the collision is elastic):

Two balls of equal masses are thrown along the same vertical direction at an interval of 2 seconds , with the same initial velocity of 1 45 ms^(-1) . Then these balls collide at a height of (use g=10 ms^(-2)

2 balls have masses of 50 gm and 100 gm and they are moving along the same line in the same direction with velocities of 3m/s and 1.5 m/s respectively. They collide with each other and after the collision, the first ball moves with a velocity of 2.5 m/s. Calculate the velocity of the other ball after collision.

A ball of mass 150 gm is thrown vertically upward with a velocity of 10m/sec. What is its initial momentum?
