4. In 1896 in Waco, Texas, William Crush parked two locomotives at opposite ends of a 6.4-km-long track, fired them up, tied their throttles open, and then allowed them to crash head-on at full speed in front of 30,000 spectators. Hundreds of people were hurt by flying debris; several were killed. Assuming each locomotive weighed 1.2 × 106 N and its acceleration was a constant 0.262, what was the total kinetic energy of the two locomotives just before the collision?

46. Roller coasters use some of the most sophisticated technology. Safety is a big part of that technology. One of the reasons roller coasters require such sophisticated safety computers is for insurance and legal purposes. During the 1920s, 30s and 40s, roller coasters had a reputation of being wild, rough and very dangerous. They pulled up to 12 Gs (about 120 m/s²), which often snapped peoples' necks! They also tended to derail and ram into each other. Modern day coasters are practically run by computers. Computers are so important for the safety of roller coasters, they make riding a coaster safer than walking across the street. Computer calculations make it possible to dip, loop and nearly scare you to death without harming you. In testing a model of a looping roller coaster, an engineer observes that the current design would result in a zero normal force acting on the passengers at the top of the loop. (a) If the radius of the loop is 4.0 m, what is the speed of the model coaster…

A car (mass 1000 kg) is traveling at 60 mph (26.82 m/s) when the driver notices a cat 50 m ahead in the road. Wanting to save the feline's life, the driver slams on the brakes and comes to a stop 2 m in front of the cat. What was the car's acceleration as it was braking?
You are playing a game and you push a cart to give it in. speed. The cart starts at the bottom (zero) of a ramp and after reaching the top of the ramp, the cart travels across a horizontal track w/ friction. The mass of the cart is 44 x 10^-3 kg. The ramp is 56 cm high. The length is 70 cm. What can you infer of the intial speed in (m/s)
3. An urban myth states that a penny dropped from the top of the Empire State Building (1440 ft tall) in NYC could be lethal. Ignore air friction and find the final velocity of the penny.
8. A tow truck finally arrives to relieve Granny. Once the car (m = 1600 kg) was hitched up, it was towed from rest to 25 m/s over a distance of 200 m. how much force was applied?
1.supposed that the body with 2 kg has an initial velocity of 10m/s and is then pulled 4 meters by a force of magnitude 25N in the direction of the initial velocity, what is its final velocity?
1. A pitcher throws a baseball with mass 0.2 kg straight upward with an initial speed of 20.0 m/s. Calculate the speed (in m/s) of the baseball at a height of 15.0 m above the pitcher’s hand.
4. Agent Burt Engle is chasing some more "bad" dudes and dudettes, when he notices his fuel gauge is running close to empty. He is approaching a hill (that makes an incline of 30 degrees with the horizontal) whose height is 49 m when suddenly, while travelling at 32 m/s, the car stalls on him. He desperately tries to re-start the car, only to fail miserably. If the average resistance force is 300 N, and the car has a mass of 800 kg, will Agent Burt Engle make it to the crest of the hill (or will he have to call Agent 001 for some back up)?
6. Son Ye Jin (SYJ), 45 kg, drops from a helicopter 4 km above the ground. Assume the air resistance is proportional to the velocity of the SYJ, with k 15 N-sec/m when the chute is closed and with constant k₂ = 105 N-sec/m when the chute is open. If the chute does not open until 1 min after SYJ paraglides, when will she hit the ground?
2. A 60 kg skateboarder comes over the top of a hill at 5.0 m/s, and then skates down an increasingly steep grade to a point halfway above the bottom of the hill, before rolling out on a much gentler slope near the bottom. The boarder's speed at the bottom of the hill is 10 m/s. (Ignore friction for this problem.) 75 S (a) Is the acceleration of the boarder down the hill constant? Explain why or why not. (b) Find the net work done on the skateboarder between the top and bottom of the hill.
An aircraft lands with a velocity of 79m/s and decelerates along the runway at 1.3m/s^2. How much runway will the aircraft consume before it comes to a full stop? Neglect friction.
