Two ice-skaters of mass 120 kg and 200 kg are initially hugging on a frictionless ice surface. Ten seconds after they push off from each other, they are 8.0 cm apart. The distance moved by the skater of mass 200 kg is

Two skaters A & B of mass M and 2M are standing together on a frictionless ice surface. They push each other apart. The skater B moves away from A with a speed of 2 m/s relative to ice. The separation between the two skaters after 5 seconds will be

Two skaters A & B of mass M and 2M are standing together on a frictionless ice surface. They push each other apart. The skater B moves away from A with a speed of 2 m/s relative to ice. The separation between the two skaters after 5 seconds will be

Two skaters A and B of mass 50 kg and 70 kg respectively stand facing each other 6 metres apart. They then pull on a light rope stretched between them. How far each moved when they meet?

A man (mass =50kg ) and his son (mass =20kg ) are standing on a frictionless surface facing each other , the man pushes his son so that he start moving at a speed of 0.70ms^(-1) with respect to the man. The speed of the man with respect to the surface is:

A man (mass = 50 kg) and his son (mass = 20 kg) are standing on a frictionless surface facing each other. The man pushes his son so that he starts moving at a speed of 0.70 m s^(-1) with respect to the man. The speed of the man with respect to the surface is:

Two skaters have weight in the ratio 4:5 and are 9m apart, on a smooth frictionless surface. They pull on a rope stretched between them. The ratio of the distance covered by them when they meet each other will be
