A 0.010 - kg bullet is fired with velocity of 400 m/s into a pendulum bob which has a mass of 0.990 kg. How high does the pendulum bob (plus bullet) swing after the collision

Two marbles with masses, MA= 50g and MB = 20 g, collide on a frictionless surface. Marble A is initially moving to the right at 0.35 m/s while marble B is at rest. Calculate the magnitude and direction of their final velocities after the collision

A steel ball of mass 0.710 kg is fastened to a cord that is 89.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number i Unit (b) Number i Unit

A 9.7-g bullet is fired into a stationary block of wood having mass m = 5.02 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.603 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)

A ballistic pendulum has a mass of 1.00 kg, it hangs from a string at rest when a bullet, mass 100.0 g is fired into it. The bullets speed is 50 m/s when it hits a pendulum. The two rise together immediately following the perfectly inelastic collision. Use the conservation of momentum and energy to determine how high they rise after the Impact.

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 4.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 7.0 m/s. What is the final velocity of the glider A after collision?

. A ball of mass 0.250-kg and a velocity of 5 m/sec to the right collides head-on with a ball mass 0.800-kg that is initially at rest. No external forces act on the balls. If the collision is elastic, and the 0.800-kg ball leaves the collision with a speed of 2.38 m/sec, what is the velocity of the other ball after the collision?

A 100 kg astronaut A is moving at a velocity of 9 m/s and runs into a stationary astronaut B (mass = 150 kg). If this is an inelastic collision, what is the velocity of the astronaut B after the collision?

A steel ball of mass 0.400 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal. At the bottom of its path, the ball strikes a 2.00 kg steel block initially at rest on a frictionless surface. The collision is elastic. (a) Find the speed of the ball just after collision. m/s (b) Find the speed of the block just after collision. m/s

Two small steel balls A and B have mass 0.6 kg and 0,2 kg respectively. they are moving towards each other in opposite directions on a smooth horizontal table when they collide directly. immediately before the collision, the speed of A is 8 m/s and the speed of B is 2m/s. immediately after the collision, the direction of motion of A is unchanged and the speed B is twice the speed of A. find  the speed of A immediately after the collision.  the magnitude of the impulse exerted on B in the collision.
