    A block of mass m = 8.40 kg, moving on a horizontal frictionless surface with a speed 4.20 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.40 kg block recoils with a speed of 0.400 m/s. In the figure, the blocks are in contact for 0.200 s. What is the magnitude of the average force on the 8.40 kg block, while the two blocks are in contact?

  • Block A of mass mA is moving horizontally with speed Va along a frictionless surface

     Block A of mass mA is moving horizontally with speed Va along a frictionless surface. It collides elastically with block B of mass mB that is initially at rest. After the collision block B enters a rough surface at x =0 with a coefficient of kinetic friction that increases linearly with distance μ(x) = bx for 0 ≤ x ≤ d, where b is a positive constant. At x=d block B collides with an unstretched spring with spring constant k...

    Block A of mass, mA = 1.7 kg is shot from a spring device of spring constant, k = 700 N/m along a frictionless horizontal surface. The initial compression of the spring is 0.300 m. The shot makes the block rise to another horizontal level at a height h= 1m above the first. On this horizontal it collides with another stationary block B of mass mB = 3.5 kg. The blocks stick together and encounter a rough surface. The blocks...
