As shown in the figure, two boxes of mass and are connected by an essentially massless, non-elastic wire passing over a light, frictionless pulley. The box of mass m, is released from rest at height h above the table. Use the isolated system model to answer the following. (We assume m, > m,. Use any variable or symbol stated above along with the following as necessary: g.) (a) Determine the speed of m, just as m, hits the table. v= 5.77 Since the only force acting is the conservative force of gravity, mechanical energy is conserved. Write a statement of conservation of energy and the expressions for the change in kinetic energy and the change in gravitational potential energy. Combine these three expressions and solve for the speed in terms of known quantities. Note that you want the speed and not the velocity. (b) Find the maximum height above the table to which m, rises. hmax = 6.66 The maximum height is the distance h plus Ah the distance m, travels upward after m, lands on the…

Just a little something on momentum and kinetic energy. As a reminder, momentum is a vector and: p = mv K = 1/2 mv2 = 1/2 pv = p2/2m In terms of the dot product: v2 = v⋅v, p2 = p⋅p, and pv = p⋅v. Unlike speed vs. velocity, but like all other vectors, momentum may refer to the magnitude of the momentum vector. Now, answers the following questions: 1) A 7-kg particle goes 96 m/s. Calculate its momentum in kg*m/s. (This requires an exact answer.) 2) A 7-kg particle's momentum is (392, 61) kg*m/s. Calculate its kinetic energy. 3) A pebble and a grapefruit have the same momentum. Which has the greater kinetic energy?
We have two spheres (m and M) that are separated by a small distance; m is to the left of M. A sphere of mass m (identical to one of the two initial spheres) is moving towards m at a speed V0. Show that when M is smaller than or equal to m, there will be 2 collisions and calculate the final speeds. Show that when M is larger than m, there will be three collisions and calculate the final velocities.

Consider a disc of mass 0.44kg, with radius 0.5 m on a slope with angle 45 degrees to the horizontal. It has a good grip on the slope and does not slip. The disc is constructed so that its mass per unit area, ρ(r) = r1/2 kg m−2, with r being the radial distance in metres from the axis of the disc. What is the acceleration of the disc down the slope?
A block of mass m is at the top of an inclined plane of length L and angle 0. At the bottom of the plane there is a relaxed spring with spring constant k. (See the figure.) The block is released from rest and slides without friction down the plane. At the bottom of the plane, the block strikes the spring and momentarily comes to rest by compressing the spring by some amount D. (a) Find D in terms of m, k, L, g, and 0. (b) Describe in words what the motion will look like over time.
