There is a 1.3 kg box moving along a horizontal frictionless floor with a velocity of 5.0 m/s. After traveling 2.0 meters it presses against a spring with spring constant 12.5 N/m. By how much will the spring be compressed when the block is at rest? a) How much energy does the system have initially? b) By how much will the spring be compressed when the block is at rest c) If instead of a frictionless surface, a section of the (0.5 meters) floor was replaced by a rougher surface that resulted in a coefficient of friction of 0.3 between the box and the surface. How much work would be done on the block when it travels over this rough surface?

A block with a mass of 2.0 kg is held against a spring with a spring constant 250 N/m. The block compresses the spring 22 cm from the equilibrium position. After the block is released, it travels along a frictionless surface and then up a ramp, μ= 0.25 The ramp’s inclination is 30° as shown below. a) Determine the elastic potential energy stored in the spring before the mass is released. b)Calculate the speed of the block as it travels along the horizontal surface. c) Determine how far along the ramp the block will travel before it stops?

A 20 kg pulley with a 0.5 m radius is initially at rest. The rotational inertia of the pulley is 0.47 mr2. A 10 kg box hangs from a rope that is wrapped around the pulley that is also initially at rest. The box falls a set distance and gains a velocity of 8 m/s. Calculate the distance that the box fell to reach that velocity.
