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

Two objects of masses 100 g and 200 g are moving along the same line and direction with velocities of 2ms^(-1) and 1ms^(-1) respectively. They collide and after the collision, the first object moves with a velocity of 1.67ms^(-1) Determine the velocity of the second object.

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

Two solid subber balls A and B having masses 0.2 and 0.4 are moving in opposite directions with velocity of A equal to 0.3 ms^-1 After collission, the two balls come to rest when the velocity of B is

An object is dropped from a height of 120 m. The acceleration of the object is 10m/s downwards. Find the distance travelled by the object after 1s. What is the final velocity of the object after 3s?
