Problem 1: (4 points) A block of mass m = 22.5 kg is being pulled at constant speed by a rope. The rope is inclined at θ = 20.00 above the horizontal, and the cart moves a distance d-20.0m on a horizontal rough surface. The coefficient of kinetic friction between the ground and cart is μ-0.5. a) what is the tension in the rope? b) How much work is done on the cart by the rope? How much work is...

Review Constants part. Consider the system of two blocks shown in (Figure 1). The blocks are released from rest. While the two blocks are moving, the tension in the light rope that connects them is 35.0 N. Part 6 If the work-energy theorem is applied to the two blocks considered together as a composite system, use the theorem to find the network done on the system during the 0.900 m downward displacement of the 6.00 kg block.

Two blocks (M1=5 kg and M2=3 kg) are
stacked on a frictionless surface but there is friction between
them. The coefficient of static friction between the blocks is
μs=0.6 and the coefficient of kinetic friction is
μk=0.3. If a person applies a horizontal force F=60 N to
M1, the blocks move. You do not know if the blocks slip
or accelerate together until you check.

A mass m1 = 5.7 kg rests on a frictionless table and connected by a massless string to another mass m2 = 5.8 kg. A force of magnitude F = 44 N pulls m1 to the left a distance d = 0.89 m. How much work is done by the force F on the two block system? How much work is done by the normal force on m1 and m2? What is the final speed of the two blocks? How...

Two blocks of masses 20 kg and 8.0 kg are connected together by a light string and rest on a frictionless, level surface. Attached to the 8.0-kg mass is a second light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 1.0 m/s2, what is the tension in the second string attached to the 8.0-kg mass? a. 6.0 N b. 4.0 N c. 14 N d. 28 N

Two blocks of masses 20 kg and 8 kg are connected together by a light string and rest on a frictionless level surface. Attached to the 8 kg mass is another light string, which a person uses to to pull both blocks horizontally. If the two block system accelerates at 0.50 m/s2 what is the tension in the connecting string between the blocks?
