A block A of mass m1 rests on a horizontal table. A light string connected to it passes over a frictionless pulley at the edge of table and from its other end another block B of mass m2 is suspended. The coefficient of kinetic friction between the block and the table is μk. When the block A is sliding on the table, the tension in the string is:

An explosion breaks a rock into three parts in a horizontal plane. Two of them go off at right angles to each other . The first part of mass 1kg moves with a speed of 12m/s^-1 and the second part of mass 2kg moves with 8m/s^-1. If the third part flies off with a velocity of 4m/s^-1 , its mass would be
