A cart of mass m1 on a horizontal track has a rocket attached to it. The rocket burns and delivers a thrust of F for t seconds. There is a second cart of mass m2 on the same track. Compare the final speeds of the carts given the two scenarios below:The rocket is fired and is allowed to speed up the cart to its maximum speed before being used up. After the rocket has burned out the first cart collides with the second cart and both lock together and move together.The carts begin locked together and the rocket propels both carts to their maximum speed.

A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
A toy car with a mass of 128 g moves to the right with a speed of 0.810 m/s. A small child drops a 30.0-g piece of clay onto the car. The clay sticks to the car and the car continues to the right. What is the change in speed of the car? Consider the frictional force between the car and the ground to be negligible. -0.15 m/s
A 59.5 kg man standing on a frictionless surface pushes two large boxes in opposite directions as shown. Initially everything is a rest. If the left box has mass 41.5 kg and final speed 3.25 m/s, and the right box has mass 27.0 kg and final speed 2.00 m/s, what is the final velocity (magnitude and direction) of the man? Let the positive direction be to the right.

A man that weights 93kg sits on a 210 kg boat. After deciding he wants to stay at his current location with his boat motionless, he throws an anchor that weights 32 kg horizontally with the speed of 4.4m/s. Assume there is no resistance from the water. What is the velocity of the boat with man after the anchor was thrown? draw a picture round significant figures show work
As shown in the figure below, cars #1 and #2 are sliding across a horizontal frictionless surface. The cars are equipped with a coupling arrangement similar to the one on railroad cars. Car #1 overtakes car #2 and they have a totally inelastic collision and become coupled together. You know the mass of each car; m, = 11.5 kg and m, = 44.0 kg. In addition, you are provided with the following graph, which shows the momentum of car #1 before, during and after the collision. p (kg m/s) 100 40 t (s) Determine the velocity (in m/s) of car #2 before the collision. m/s
A 0.020 kg bullet is shot horizontally and collides with a 2.00 kg block of wood. The bullet embeds in the block and the block slides along a horizontal surface for 1.50 m. If the coefficient of kinetic friction between the block and the surface is 0.400, what was the original speed of the bullet? Include a diagram of the situation.
A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What is the speed of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small. Please answer in units of m/s.
A rocket burns in 2 stages. In stage 1, .35mo is burned. It then releases the first stage tank (of mass .1mo ), and then burns the 2nd stage (.25mo). It does not release the second tank afterwards. What is the final speed of the rocket assuming no external forces are present?
As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 4.63 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.25 kg, determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure. y1f=____m y2f=____m
An ice skater with a mass of 48.0 kg is gliding across a smooth lake with a speed of 2.85 m/s when she hits a spot of ice covered with snow. After a time of 7.75 s she has slowed to a stop. Using your knowledge of momentum, determine the magnitude of the average force of friction acting on the ice skater while she slows to a stop.
