Two billiard balls are rolling on a flat table. One has the velocity components v_(x) = 1 ms^(-1), v_(y) = sqrt(3)ms^(-1) and the other has components v'_(x) = 2ms^(-1) and v'_(y) = 2ms^(-1) . If both the balls start moving from the same point, what is the angle between their paths ?

Two billiard ball, rolling a flat table, have started moving from the same point. If their x components of velocities are sqrt3m//s and 2m//s and y components of velocities are 1m//s and 2m//s , respectively, calculate the angle between their paths .

A boy throws a ball at an angle theta with the vertical. If the vertical component of the initial velocity is 20ms^(-1) and the wind imparts a horizontal acceleration of 8ms^(-2) to the left, the angle at which the ball must be thrown so that the ball returns to the boy's hand is theta . What is the value of 10(tan theta)

Three small balls of masses 1kg, 2kg and 3kg are moving in a plane and their velocities are 1 ms^(-1) ,2ms^(-2) and 3ms^(-1) respectively as shown . The total angular momentum of the system of three balls about point P at the given instant of time is

A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:

Two balls are moving on the same smooth horizontal plane. Their velocity components along one adge of the square plane are 10sqrt(3)m//s & 20 m//s respectively. Their velocity components along a perpenficular edge are 30 m//s & 20 m//s . Find the angle between their directions of motion.

Two billiard balls each of mass 0 .05 kg moving in opposite directions with speed 6 ms^(-1) collide and rebound with the same speed What is the impulse imparted to each ball due to the other ?

A rocket is moving in a gravity free space with a constant acceleration of 2ms^(-1) along +x direction (see Fig.5.126). The length of a chamber inside the rocket is 4m. A ball is thrown from the left end of the chamber in +x direction with a speed of 0.3 ms^(-1) relative to the rocket. At the same time , another ball is thrown in -x direction with a speed of 0.2ms^(-1) from its right and relative to the rocket. the time in seconds when the two balls hit each other is:

A box B_(1) contains 1 white ball, 3 red balls, and 2 black balls. An- other box B_(2) contains 2 white balls, 3 red balls. A third box B_(3) contains 3 white balls, 4 red balls, and 5 black balls. If 2 balls are drawn (without replecement) from a randomly selected box and one of the balls is white and the other ball is red the probability that these 2 balls are drawn from box B_(2) is

A train is moving along a straight line with a constant acceleration a. A body standing in the train throws a ball forward with a speed of 10ms^(-1) , at an angle of 60^(@) to the horizontal . The body has to move forward by 1.15 m inside the train to cathc the ball back to the initial height. the acceleration of the train. in ms^(-2) , is:
