- Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 140,000 kg and a velocity of 0.300 m/s, and the second having a mass of 95,000 kg and a velocity of −0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)?A bullet is fired into a block of wood sitting on a block of ice. The bullet has an initial velocity of 500m/s and a mass of 0.005kg. The wooden block has a mass of 1.2kg and is initially at rest. The bullet remains embedded in the block of wood afterward. a) Assuming that the momentum is conserved, find the velocity of the block of wood and bullet after the collision. b) What is the magnitude of the impulse that acts on the block of wood in this process? c) Does the change in momentum of the bullet equal that of the block of wood?A 60-kg swimmer suddenly dives horizontally to the left from a 100-kg raft with a speed of 2.5 m/s. The raft is initially at rest. What is the velocity of the raft immediately after the diver jumps?
- A 170-g billiard ball is shot toward an identical ball at velocity vi = 6.90 m/s.The identical ball is initially at rest. After the balls hit, one of them travels with velocity v1, f = (1.65 + 2.10) m/s. What is the velocity of the second ball after the impact? Ignore effects of friction during this process. (Express your answer in vector form.)Car A is moving to the right at 0.5m/s. Meanwhile, Car B, which is 6 meters to the right of car A is moving to the left at 0.25m/s. Looks like they’re going to have a head-on collision. Predict the location of the collision.Two 2712 kg train cars roll toward each other (Car A at 0.34 m/s, Car B at -2.5 m/s) on a level track. After they collide and couple together, what is the final velocity of the two-car object?
- An elastic collision occurs in one dimension, in which a 10 kg block traveling at 5 m/s collides with a 5 kg block traveling at 3 m/s in the same direction. What are the velocities of the two blocks immediately after the collision?Mr. H ignites the enthusiasm of the class with a home-made cannon demonstration. The 1.27-kg cannon is loaded with a 54-gram tennis ball and placed on the floor. Mr. H adds the fuel, waits for its vapors to fill the reaction chamber and then brings a match nearby. The explosion stuns the crowd and propels the ball forward. A photogate measurement determines that the cannon recoiled backwards with a speed of 7.8 m/s. Determine the speed of the ball.The cue ball A is given an initial velocity (VA)₁ = 5 m/s. If it - makes a direct collision with ball B (e = 0.73) determine the angle just after ball B rebounds from the cushion at C (e' = 0.6). Each ball has a mass of 0.4 kg. Neglect the size of each ball. Give your answer in degrees with one decimal place of precision. (VA)₁ = 5 m/s B 30°
- To Mr. H's disgust, a 450-g black crow is raiding the recently-filled bird feeder. As Mr. H runs out the back door with his broom in an effort to scare the crow away, it pushes off the 670-gram feeder with a takeoff speed of 1.5 m/s. Determine the speed at which the feeder initially recoils backwards.Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 180,000 kg and a velocity of 0.300 m/s,and the second having a mass of 95,000 kg and a velocity of −0.120 m/s.

Bob who weighs 490 N runs at 2 metres per second and jumps on the sled. A few seconds later, Tom who weighs 540N runs at 4 metres per second and jumps on the sled with Bob. Keep all values to 3 decimal places. A)What is the velocity of the sled after Bob jumps on to it? B)What is the velocity of the sled after Tom jumps on it?
