High-speed stroboscopic photographs show that the head of a 220-g golf club is traveling at 41 m/s just before it strikes a 46-g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 31 m/s. Find the speed of the golf ball just after impact.

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 ?

Shown is a collision between two pucks on an air hockey table. Puck a has mass 0.025kg and is moving along the x-axis with a velocity of +5.5m/s. It makes a collision with puck B, which has a mass of 0.05kg and is initially at rest. The collision is not head-on. After the collision the pucks fly off with the angles as shown. +5.5 m/s At rest Before collision 65 37- After collision What is the speed of puck A? (4) m/s What is the speed of puck B? (4) m/s

A thin block of soft wood with a mass of 0.072 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 577 m/s at a block of wood and passes completely through it. The speed of the block is 22 m/s immediately after the bullet exits the block. (a) Determine the speed (in m/s) of the bullet as it exits the block. m/s (b) Determine if the final kinetic energy of this system (block and bullet) is equal to, less than, or greater than the initial kinetic energy. O equal to the initial kinetic energy less than the initial kinetic energy greater than the initial kinetic energy (c) Verify your answer to part (b) by calculating the initial and final kinetic energies of the system in joules.

A 2.8 kg block of wood sits on a frictionless table. A 3.0 g bullet, fired horizontally at a speed of 510 m/s , goes completely through the block, emerging at a speed of 210 m/s . What is the speed of the block immediately after the bullet exits?

The A hockey puck moving at 0.49 m/s collides elastically with another puck that was at rest. The pucks have equal mass. The first puck is deflected 37° to the right and moves off at 0.36 m/s. Find the speed and direction of the second puck after the collision. magnitude direction m/s to the left

A 0.15 kg baseball is struck by a bat with a contact time of 0.008 seconds. The ball leaves the bat with a speed of 45 m/s (parallel to the ground). What is the force imparted on the baseball by the bat? Assume this is an elastic collision.

A 8.0kg puck floating on an air table is traveling east at 10cm/s. Coming the other way at 30cm/s is a 2.0kg puck on which is affixed a wad of bubble gum.The two slam head-on into each other and stick together. a) Find their velocity after the impact.b) How much kinetic energy is lost?

A 25.0 g bullet traveling horizontally at 500 m/s strikes a 0.750 kg block of wood that is balanced on the edge of a table 0.800 m above the floor. If the bullet embeds itself into the block, then (a) how fast is the bullet and block combination moving immediately after the collision and (b) how far horizontally from the edge of the table will the bullet and block combination hit the floor? Include a diagram of the situation as needed.

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?
