Consider the collision depicted in figure to be between two billiard balls are equal masses m_(1)=m_(2) . The first ball is called the cue while the second ball is called the target . The billiard player wants to 'sink ' the target ball in a corner pocket , which is at angle theta_(2) = 37^(@) .Assume that the collision is elastic and that friction and rotational motion are not important . Obtain theta_(1) .

Two identical small balls each of mass m are rigidly affixed at the ends of light rigid rod of length 1.5 m and the assmebly is placed symmetrically on an elevated protrusion of width l as shown in the figure. The rod-ball assmebly is titled by a small angle theta in the vertical plane as shown in the figure and released. Estimate time-period (in seconds) of the oscillation of the rod-ball assembly assuming collisions of the rod with corners of the protrusion to be perfectly elastic and the rod does not slide on the corners. Assume theta=gl (numerically in radians), where g is the acceleration of free fall.

Two balls marked 1 and 2 of the same mass m and a third ball marked 3 of mass M are arranged over a smooth horizontal surface as shown in the figure. Ball 1 moves with a velocity v_(1) towards ball 2. All collisions are assumed to be elastic. If Mltm , the number of collisions between the balls will be.

A car P is moving with a uniform speed 5sqrt3 m//s towards a carriage of mass 9 kg at rest kept on the rails at a point B as shown in figure. The height AC is 120 m. Cannon balls of 1 kg are fired from the car with an initial velocity 100m//s at an angle 30^@ with the horizontal. The first cannon hall hits the stationary carriage after a time t_0 and sticks to it. Determine t_0 . At t_0 , the second cannon ball is fired. Assume that the resistive force between the rails and the carriage is constant and ignore the vertical motion of the carriage throughout. If the second ball also hits and sticks to the carriage, what will be the horizontal velocity of the carriage just after the second impact?

A gun which fires small balls of mass 20 g is firing 20 balls per second on the smooth horizontal table surface ABCD . If the collision is perfectly elastic and balls are striking at the centre of table with a speed of 5 m//s at an angle of 60^(@) with the vertical just before collision, then force exerted by one of the legs on ground is (assume total weight of the table is 0.2 kg )

A rectangular plate of mass M and dimension axxb is held in horizontal position by striking n small balls (each of mass m) per unit area per second. The balls are striking in the shaded half region of the plate. The collision of the balls with the plate is elastic. What is v? (Given n=100, M =3 kg, m=0.01 kg, b = 2m, a =1m, g = 10m/s^2).

Two identical small elastic conducting balls of mass m and radius r have charges of oppsite signs Q and -q. Inditially they are held in free space with their centres at separation lgt 2r and then released Their speeds v long after their collision is v=sqrt((1)/(axxpiepsilon_(0)m){((Q+q)^(2))/(bxxr)-(Qq)/(l)}) (Ignore non-uniformity in charge distributuion when ball come close to each other, magnetic field produced by motion of charges and the gravitational interaction between them). Find ((6xxaxxbxx)/(48) ? (a and b are lowest possible integers)
