Two blocks are connected by a string that passes over a pulley, as shown in the figure. The pulley rotates without friction and its mass can be neglected. Block A 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/s^2g=10m/s2. When the system is released from rest, block A accelerates up the slope and block B accelerates straight down.
a)
Block A has a mass of 3.00 kg. When block B has fallen through a height h = 2.00 m, its speed is v = 4.00 m/s.
Assuming that no friction is acting on block A, what is the mass
of block B?
_______ kg
b)
Block A has a mass of 3.00 kg. When block B has fallen through a height h = 2.00 m, its speed is v = 4.00 m/s.
If, instead, there is friction acting on block A, with a
coefficient of kinetic friction of 5/8, what is the mass of block
B?
_______ kg

Two blocks are connected by a string that passes over a frictionless pulley, as shown in the figure. The pulley has a mass of mp = 2.00 kg, and can be treated as a uniform solid disk that rotates about its center. Block A, with a mass = 3.00 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, torques,...

14. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a frictionless 30.0 degree incline. The vertically hanging mass is 6.00 kg and the mass on the incline is 4.00 kg. The magnitude of the acceleration of the 4.00 kg mass is 15. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs...
Two blocks are connected to a string, and the string is hung over a pulley connected to the ceiling, as shown in the figure below. Two blocks, labeled m1 and m2, are connected to a string which is hung over a pulley connected to the ceiling. The pulley is of mass M and radius R. A block labeled m1 hangs suspended off the surface on the left side of the pulley. A block m2 is on the right side of...
Two blocks are connected by a string that is wrapped around a pulley wheel. The light block with mass 5.3 kg sits a flat table; the heavier block, which is twice as massive, is suspended below the pulley. There is friction acting between the lighter block and the table with a coefficient of friction 0.79. The system is released from rest. What is the speed of the blocks after the bottom block has fallen 4.2 meters in units of meters/second?...
Two blocks are connected by a light string that passes over a frictionless pulley as in the figure below. The system is released from rest while m2 is on the floor and m1 is a distance h above the floor. (a) Taking m1 = 6.4 kg, m2 = 3.9 kg, and h = 3.1 m, find the final speed. (b) Find the speed of each block when m1 has fallen a distance of 1.3 m.
Two blocks start from rest and are connected by a string that
passes over a pulley, as shown in the picture below. The pulley is
a uniform disk of mass
mp = 4.00 kg; m = 5.00 kg and M = 11.0 kg. For both blocks, ?k =
0.240. If the speed of the blocks is 1.50 m/s after they have moved
a distance of 2.00 m, find ?.
