If a shopping cart with a mass of 25kg is pushed with a net force of 60 N, what will be the cart's acceleration?
Two different air track carts are sliding to the right at 1.0 m/s. The leading cart has a mass of 500g and the trailing cart has a mass of 200g. They are being held together by a string, but being pushed apart by a spring between the two carts. The spring between them has a spring constant of 150 N/m and is compressed 4.0 cm. At t=0, the string is snipped. What are the final velocities of both carts? Don’t...
4. Two carts collide and stick together in a lab experiment. Cart 1 has a mass of 550 g and a speed before the collision of 2.5 m/s. Cart 2 has a mass of 320 g and a speed of -4.1 m/s. Consider the 2 carts to be the system. A. What is the total momentum of the system before the collision? B. What is the velocity of the 2 carts after the collision? C. If the collision takes 0.15s,...

Two carts are sitting on air track (frictionless surface). Assume cart A has mass of .50 kg, cart B has mass of 1.0 kg. You push cart A and give it an initial speed of 5.0 m/s toward B which was originally at rest. The two carts stick together and move together. Right after collision, the air is turned off so the two carts slide to a stop due to kinetic friction. Assume the coefficient of kinetic friction is .20....
Two carts are on an air track (no friction). The first cart, with a mass of 1.0 kg, is traveling at 1.0 m/s towards a second stationary cart, of mass 0.7 kg. Both carts have Velcro bumpers and attach to each other after the collision. What is the final speed of both carts after the collision? (5 marks)
Problem 1: (4 points) A block of mass m = 22.5 kg is being pulled at constant speed by a rope. The rope is inclined at θ = 20.00 above the horizontal, and the cart moves a distance d-20.0m on a horizontal rough surface. The coefficient of kinetic friction between the ground and cart is μ-0.5. a) what is the tension in the rope? b) How much work is done on the cart by the rope? How much work is...
A grocery cart with mass of 16 kg is being pushed at constant speed up a 12∘ ramp by a force FP which acts at an angle of 17∘ below the horizontal. a) Find the work done by the force F⃗ P on the cart if the ramp is 7.5 m long. b) Find the work done by the force mg⃗ on the cart. c) Find the work done by the force F⃗ N on the cart.
There are two carts colliding in elastic collision. Initial conditions: Cart 1 has unknown mass and is traveling at 30cm/s. Cart 2 has the mass of 150g and is travelling at 30cm/s. Final Conditions: Velocity of Cart 1 is 0 and the Velocity of Cart 2 is Unknown. What is the Final Velocity of Cart 2 and the Mass of Cart 1?
Exam 3 (cont.) 19. 8 of 12 Consider two carts of mass m and 4m, at rest on a frictionless, horizontal surface. Now suppose a horizontal force is exerted on each cart. The forces are constant, and they have the same magni- tude F, and the same direction. The force on m acts for 2 seconds and the force on 4m acts for 1 second. After the forces cease, the carts continue moving with constant velocity forever. Compare the momenta...
