7. A 5.20 g bullet moving at 672 m/s strikes a 700 g wooden block at rest on a
frictionless surface. The bullet emerges, traveling in the same direction with its speed
reduced to 428 m/s. (a) What is the resulting speed of the block? (b) What is the
speed of the bullet-lock center of mass?

A 0.0210 kg bullet moving horizontally at 450 m/s embeds itself into an initially stationary 0.500 kg block. (a) What is their velocity (in m/s) just after the collision? m/s (b) The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.30 kinetic coefficient of friction. Now what is its velocity (in m/s)? m/s (c) The bullet-embedded block now strikes and sticks to a stationary 2.00 kg block. How far (in m) does this combination travel before stopping? m

A bullet, m = 2.00 kg, traveling with a velocity of 60.0 m/s strikes and embeds itself in the bob of a ballistic pendulum, M = 8.00 kg, which swings on a frictionless axis as shown. The combined masses rise to a height h above the bob's initial position. M Determine the height h (shown) that the combined block-bullet system rises to after collision. 7.35 m 6.00 m O 1.22 m 12.5 m
You launch a 20 kg shell at 45 degrees and at a speed of 25 m/sec. 1 second after launching it, it explodes into two fragments. Note that the first fragment of 15 kg has a speed of 30 m/sec horizontally forward immediately after the explosion. What is the speed of the second fragment ?
A 61g ball traveling at 6.3 m/s is caught by a 220g pendulum bob. The center of mass of the pendulum / ball system reaches a maximum height of 10.4 cm (relative to the initial rest position) after the collision. Calculate the kinetic energy of the pendulum/ball system in the instant after the collision (Kball+bob). Use L=30.2cm and R=26.3cm
In the figure here, a 7.0 g bullet moving directly upward at 870 m/s strikes and passes through the center of mass of a 6.8 kg block initially at rest. The bullet emerges from the block moving directly upward at 410 m/s. To what maximum height does the block then rise above its initial position?
A 2x103 g metal sphere makes an elastic collision with another metal sphere at rest and continues to move in its original direction but with 1/4 its original speed. What is the speed of the two-sphere center of mass if the initial speed of the first sphere is 4m/s? (Answer in one decimal place, no unit) UNIT: m/s Add your answer
An open train car, with a mass of 2050 kg, coasts along a horizontal track at the speed 2.792.79 m/s. The car passes under a loading chute and, as it does so, gravel falls vertically into it for 2.792.79 s at the rate of 475 kg/s. What is the car's speed vf after the loading is completed? Ignore rolling friction.
A 28-g bullet moving horizontally strikes and remains in a 2.6-kg block initially at rest on the edge of a table. The block, which is initially 88 cm above the floor, strikes the floor a horizontal distance of 113 cm from its initial position. What was the initial speed of the bullet?
A 25.00 kg wrecking ball is hanging from a hook by a wire of negligible mass, 2.5 m long and is free to swing in a complete circle. It is struck horizontally by a smaller wrecking ball of mass 3.00 kg in a perfectly elastic collision. What must be the minimum initial speed of the smaller ball so that the 25.00 kg ball makes a complete circular loop after the collision?
