A bombshell of mass explodes such that the broken masses are in the ratio 1 : 1 : 3 . The ratio two pieces of equal mass fly with the same speed at right angles to each other with a velocity of 100ms^(-1) . Find the direction and velocity of the third fragment of the shell. What will be the total kinetic energy of the fragments.

A car of mass 2000 kg is lifted up a distance of 30m by a crane in 1 min. A second crane does the same job is 2 min. What is the power applied by each crane? Do the crnae? Do the caranes consume the same or different amount of fule? Neglect power dissipation against friction.

A 2kg mass is attached to a spring of force constant 600 N//m and rests on a smooth horizontal surface. A second mass of 1kg slides along the surface toward the first at 6m//s . (a) Find the amplitude of oscillation if the masses make a perfectly inelastic collision and remain together on the spring. what is the period of oscillation ? (b) Find the amplitude and period of oscillation if the collision is perfectly elastic. ( c) For each case , write down the position x as a function of time t for the mass attached to the spring, assuming that the collision occurs at time t = 0 . What is the impulse given to the 2kg mass in each case ?
