A block movig horizontally ona smooth surace with a speed of 20 m/s bursts into thwo equal parts cobtinuing in the same direction. If one of the parts moves at 30 m/s, with whast speed does the second part move and what is tehfractional change in the kinetic energy?

A block moving horizontally on a smooth surface with a speed of 20 m/s bursts into two equal parts continuing in the same direction. If one of the parts moves at 30 m/s, with what speed does the second part move and what is the fractional change in the kinetic energy?

A block moving horizontally on a smooth surface with a speed of 40 m/s splits into two parts with messes in the ratio of 1:2 If the smaller part moves at 60 m/s in the same direction , then fractional change in kinetic energy is :

A block moving horizontally on a smooth surface with a speed of 40 ms^(-1) splits into two equal parts. If one of the parts moves at 60 ms^(1) in the same direction, then the fractional change in the kinetic energy will be x : 4 where x =__________

A light particle moving horizontally with a speed of 12 m//s strikes a very heavy block moving in the same direction at 10 m//s . The collision is one-dimensional and elastic. After the collision, the particle will

A projectile is moving at 60 m//s at its highest point, where it breaks into two equal parts due to an internal explosion. One part moves vertically up at 50m//s with respect to the ground. The other part will move at

A shell of 20kg moving at 50m/s bursts into two parts of masses 15kg and 5kg .If the larger part continues to move in the same direction at 70m/s .What is the velocity and direction of motion of the other piece.
