A 2.70-kg ball, moving to the right at a velocity of +3.39 m/s on a frictionless table, collides head-on with a stationary 7.10-kg ball. Find the final velocities of (a) the 2.70-kg ball and of (b) the 7.10-kg ball if the collision is elastic. (c) Find the magnitude and direction of the final velocity of the two balls if the collision is completely inelastic.
The rms speed of a sample of gas is increased by 3 percent. What is the percent change in the temperature of the gas? What is the percent change in the pressure of the gas, assuming its volume is held constant?
In a ballistics test, a 23-g bullet travelling horizontally at 1300 m/s goes through a 40.0 cm-thick 450-kg stationary target and emerges with a speed of 900m/s. The target is free to slide on a smooth horizontal surface.
