Arnima is driving a 1250 kg car at 120 km/h and runs into a 520 kg moose eating grass (stationary). The road is W 22° S. Upon impact, the moose dies - the collision is inelastic. Find the final velocity of the moose and car.

A 0.507-kg ball, initially moving with a speed of 3.49 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 6.7 ms, what is the magnitude of the average force that the wall exerts on the ball? Express ans in 2decimal places, in Newtons.

A 0.25-kg ball, initially at reston a tee, is hit with a bat in the x-direction while 1.00 meter above the ground. If the ball hits the ground 20 meters away and was in contact with the bat for 0.10-s, what average force was exerted on the ball during the contact time?   Answer: 111 N

a billiard ball moving at 5.00m/s strikes a stationary ball of the same mass. After the collision, Ball #1 moves at a speed of 4.35 m/s. Find the speed of ball #2 after the collision.

What is the velocity (in m/s) of a 905 kg car initially moving at 25.0 m/s, just after it hits a 125 kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car. (Enter the magnitude.)

20 kg and m2 = 5 kg. Vii = 40 m/s and 4. Find the velocity of m1 and m2 after collision. m1 V2i – 20 m/s. Assume the collision is elastic. m2 V2i

A Z Olaf is standing on a sheet of ice that covers the football stadium parking lot in Buffalo, New York; there is negligible friction between his feet and the ice. A friend throws Olaf a ball of mass 0.400 kg that is traveling horizontally at 10.8 m/s. Olaf's mass is 69.7 kg.( Figure 1) 2 masteringphysics.com/mycitemView?assignment ProblemID=189028758&offset=next W S Figure X command A # 3 20 E D C $ B 4 888 R F I % 5 of V 254 FD T G 6 B Part A 20 If Olaf catches the ball, with what speed ty do Olaf and the ball move afterward?

A firework is launched and has a strictly vertical trajectory. It has velocity of 30 m/s right before it explodes. After it explodes, it instantaneously splits into three projectiles of equal mass. One of the projectiles continues to travel straight upwards with a velocity of 50 m/s. The right-most projectile now has an upward velocity of 45 m/s at 25◦ right of vertical. What is the final velocity of the left-most projectile?
