3. Coal miners love physics, and in their spare time, they like to do physics experiments. One popular experiment involves using a sling shot to shoot lumps of coal into coal carts and seeing how far the carts move along the track as a result. One particular miner shoots a 5.0-kg lump of coal horizontally off a 10-m high ledge into a 90-kg cart waiting below, as shown. If the lump of coal has an initial speed of 30 m/s and the cart moves 0.80 m after the coal lands inside it, how much work did the friction between the cart and the track do on the cart? Also, what is the coefficient of kinetic friction between the cart and the track? Hint: you can assume that friction is the only force acting on the cart in the horizontal direction.
A bullet of mass 52 grams is fired horizontally into a 5.2 kg wooden block on a horizontalsurface. The coefficient of kinetic friction between the block and the surface is 0.52. Thebullet stops in the block which slides straight ahead for 5.2 meter. At what speed is thebullet fired?(Apply conservation of energy with friction

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER When serving a tennis ball, the player hits it when its velocity is zero (at the highest point of a vertical toss). The racket exerts a force of 560 N on the ball for 5.00 ms, giving it a final velocity of 44.0 m/s. Using these data, find the mass (in g) of the balI.
onstants Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of Part A 2.0 km and a mass of 1.0 xX 1013 kg hits the earth (6.0 x 1024 kg) with an impact speed of 3.8 × 104 m/s. What is the earth's recoil speed after such a collision? (Use a reference frame in which the earth was initially at rest.) Express your answer with the appropriate units. • View Available Hint(s) HẢ ? Value Units V =
Q8/ Two locomotives at opposite ends of a 7-km-long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed. Assuming each locomotive weighed 2 x 10° N and its acceleration was a constant 0.2 m/s, what was the total kinetic energy of the two locomotives just before the collision?

A shell is shot with an initial velocity of 17 m/s, at an angle of 0o = 64° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that air drag is negligible? Explosion

Muskox: In the arctic, male muskoxen compete for the attention of females by butting heads. On a cold day (-16.3 degree F), a young bull spies an older bull 13.9 m away and charges! The two meet in a head-on collision and come to a complete stop. The young bull has a mass of 681 kg and was running at a speed of 9.5 m/s. The older bull has a mass of 654 kg. The collision takes place on an icy patch, so you can ignore friction. (a) What was the speed of the older bull? (b) How many joules of energy were "lost" in this collision?
