6.A 93.5 kg ice hockey player hits a 0.150 kg puck, giving the puck a velocity of 43.0 m/s. If both are initially at rest and if the ice is frictionless, how far does the player recoil in the time it takes the puck to reach the goal 17.0 m away?
1. A firecracker travels straight up at 75.0m/s and explodes into two pieces. The smaller piece carries one third of the firecracker's mass and shoots off horizontally at 48.0m/s west. Determine the speed and direction of the other piece directly after the explosion. 2. Three blocks slide on a smooth surface. Initially, the first block (m1=1.0kg) moves at 3.0m/s to the right, the second block (m2=2.0kg) is at rest, and the third block (m3=3.0kg) moves to the left at 0.50m/s. First, m1 collides elastically with m2 and recoils to the left. Afterwards, m2 and m3 collide and stick. Calculate, a. the velocities of m1 and m2 after the first collision. b. the velocity of m2 and m3 after the second collision.
4. A block of mass 1.90 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 3.59 m/s. It eventually collides with a second, stationary block, of mass 4.53 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.90-kg and 4.53-kg blocks, respectively, after this collision? 1.47 m/s and 2.12 m/s 2.12 m/s and 1.47 m/s 2.68 m/s and 1.80 m/s 1.03 m/s and 1.64 m/s
8. A hockey puck (1) of mass 140 g is shot east at a speed of 7.00 m/s. It strikes a second puck (2), initially at rest, of mass 133 g. As a result of the collision, the first puck (1) is deflected at an angle of 60° south of east and the second puck (2) moves at an angle of 48° north of east. What is the magnitude of the velocity of puck (1) after the collision? m/s

A 7.500 E+3-kg truck moving east at 10.3 m/s collides with a 2.500 E+3-kg car moving west at 35.0 m/s. The collision takes place over a time interval of 0.5 s. The car and the truck stick together after the collision. Find the force (in N) of the car on the truck during the collision. Call this force positive if it points to the east, and negative if it points to the west. (Could you give an explanation on how to transfer/ convert E +3)
As shown below, a 850 kg car traveling east collides with a 1780 kg pickup truck that is traveling north. The two vehicles stick together as a result of the collision. After the collision, the wreckage is sliding at vf = 14 m/s in the direction ? = 21° east of north. Calculate the speed of each vehicle before the collision. The collision occurs during a heavy rainstorm so you can ignore friction forces between the vehicles and the wet road. Express your answers using apropriate mks units. A.) vcar,i = B.) vtruck,i = C.) Determine what fraction of the total initial KE is turned into thermal energy as a result of the collision. ΔTE KEtotal,i =
1. Greg throws a small lump of clay at a larger block of clay, which is at reston a horizontal surface. The small lump has a mass of 24.0 grams. The block has a mass of 65.0 grams. The lump sticks to the block, and together they slide 1.20 m before stopping. If the speed of the lump before the collision is 5.25 m/s, what is the coefficient of friction between the clay at the surface? 2.
