In the figure below, a 3.9 kg box of running shoes slides on a horizontal frictionless table and collides with a 2.4 kg box of ballet slippers initially at rest on the edge of the table, at height h = 0.40 m. The speed of the 3.9 kg box is 5.0 m/s just before the collision. If the two boxes stick together because of packing tape on their sides, what is their kinetic energy just before they strike the floor?
Using Law of Conservation of momentum
Momentum before collision = momentum after collision
This will remain horizontal velocity at the time of collision. Now vertical velocity gain during fall
Velocity of the system just before collision
Kinetic energy before striking floor

A 4.3 kg box slides on a horizontal frictionless table and collides with a 2.7 kg box initially at rest on the edge of the table, at height h = 0.5 m. The speed of the 4.3 kg box is 2.7 m/s just before the collision. If the two boxes stick together because of packing tape on their sides, what is their kinetic energy just before they strike the floor? (Your result must be in Joules and include 1 digit...

R The left box in the figure is released and slides down a frictionless bowl with a radius of curvature R. Both boxes have the same mass m. Please show your work clearly and express all answers in terms of the given variables, m and R. If the two boxes stick together at the bottom of the bowl, a. find their speed immediately after they collide; and b.find how far up the side of the bowl the two will rise....

In the figure, block 1 of mass 2.00 kg slides from rest along a frictionless ramp from height h = 2.60 m and then collides with stationary block 2, which has mass 4.50 kg. The spring shown has a spring constant of 31.5 N/m. (a) How fast is block 1 moving just before contacting block 2? (b) Assume the whole path is frictionless, and the collision is completely inelastic, how far does the spring compress? (c) Now, assume you test...
Problem 1: An object with mass m, = 2 kg slides down a frictionless incline that makes a 25° with the horizontal (as in the figure). At the bottom of the incline, object 1 continues to travel along the rough surface with the = 0.4. Object 2, m, = 5 kg is d = 3 m away from the bottom of the incline. Object 2 is initially at rest. The height of the incline is h = 4m. h 0...
