1. Consider the setup in the figure below. The strings are massless and the pulleys are massless and frictionless. The coefficient of kinetic friction between the 2.0-kg block and the table is 0.29. What is the acceleration of the 2.0-kg block? Give your answer in m/s2. Enter only the numerical value (i.e. do not include the units!)

2. Two rocks, one of mass m and the other of mass 2m, are dropped from the top of a building. When they hit the ground

A. the heavier one will have four times the kinetic energy of the lighter one.

B. the heavier one will have twice the kinetic energy of the lighter one.

C. they will have the same kinetic energy.

D. the heavier one will have 2 times the kinetic energy of the lighter one.

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...

Constants (Figure 1)Block 1, of mass m1 = 0.600 kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. For an angle of ? = 30.0 ? and a coefficient of kinetic friction between block 2 and the plane of ? = 0.400, an acceleration of magnitude a = 0.400 m/s2 is observed for block 2. Part A Find the mass of block 2, m2. Express your answer numerically in kilograms.

Two blocks are connected by a massless string that runs across a frictionless pulley with a mass of 5.00 kg and a radius of 10.0 cm. The first block with an unknown mass of m1 sits on a horizontal surface and is also connected to a spring with a spring constant of k = 250 N/m. The coefficient of kinetic friction between the first block and the surface is 0.400. The second block with a mass of m2 = 6.00...

Two blocks, each of mass m = 6.00 kg , are connected by a massless rope and start sliding down a slope of incline θ = 36.0 ∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk = 0.300. At a distance d = 1.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks when block A reaches this frictional transition point? Assume...

The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is heavier and rests on a ramp that is less steep. The boxes are released from rest at A and allowed to slide down the ramps. The two boxes have masses of 14 and 45 kg. If A and B are hA = 4.0 and hB = 1.7 m, respectively, above the ground, determine the speed of...
