In the figure, two long barges are moving in the same direction in still water, one with a speed of 13 km/h and the other with a speed of 16 km/h. While they are passing each other, coal is shoveled from the slower to the faster one at a rate of 800 kg/min. How much additional force must be provided by the driving engines of (a) the faster barge and (b) the slower barge if neither is to change speed? Assume that the shoveling is always perfectly sideways and that the frictional forces between the barges and the water do not depend on the mass of the barges.

At an intersection, two cars have collided. Car 1 has a mass of 2200kg, moving west collided with car 2 with a mass of 1500kg moving north. The cars stuck together and skid at angle of 20 degrees north of west with a distance of 15m. Between the tires and the road, the coefficient of kinetic friction is 0.60. If the speed limit of each car was 50km/h, was either car speeding? Two things happened in this questions. There is a collision and then the cars slid to a stop together. a) consider the second scenario where the two cars were stuck and skid 15m to a stop. Using work energy Theorem, calculate the velocity righ after the collision and the two cars started to skid B) sketch the diagram of collision before and after the crash with labels of masses and velocities of both the vehicles C) from part A, we know the velocity of the two cars after collision. Determine the initial velocities of the two cars and find which car is speeding using conservation of momentum
Two figure skaters, one weighing 625 N and the other 725 N, push off against each other on very smooth ice. a)If the heavier skater travels at 1.50 m/s, how fast will the lighter one travel? b)How much kinetic energy is "created" during the skaters' maneuver?
A student of mass 63 kg falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest at a time of 0.04 seconds. The average force exerted on him by the ground is 18,000 N, where the upward direction is taken to be a positive direction. From what height did the student fall? Assume that the only force acting on him during the collision is only due to the ground

A 0.7 ball falls down and hits the floor at a speed of 15 m/s. The ball then bounces back up at aspeed of 12 m/s. If the ball was in contact with the floor for 0.06 s, what was the average force from the floor on the ball?
A soccer ball has an initial speed of 5 m/s, that goes to the right and then hits a wall. After hitting that wall, the soccer ball now goes to the left direction with a speed of 2 m/s. What is the magnitude of the force exerted by the wall to the soccer ball if the time of contact between the two is 0.02 s? Hint: Be careful with the direction of the velocities.

Jason takes off from rest across level water on his jet-powered skis. The combined mass of Jason and his skis is 75 kg (the mass of the fuel is negligible). The skis have a thrust of 200 N and a coefficient of kinetic friction on water of 0.10. Unfortunately, the skis run out of fuel after only 27 s. How far has Jason traveled when he finally coasts to a stop?
