A. A block is pulled along a horizontal surface by a force of 12.0 N. The block has a mass of 4.00 kg and it accelerates at 2.00 m/s. Find the coefficient of kinetic friction for the interface between the block and the surface. B. A stone falls vertically through the air and experiences a drag force. If the stone's mass is 6.00 kg. and the drag force (upwards force) is 14.0 N, what is the acceleration of...
A block rests on a horizontal frictionless surface. A string is attached to the block, and is pulled with a force of 59.0 N at an angle o above the horizontal.

A horizontal force of 40 N acting on a block on a frictionless level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration of the combination of blocks if the same force continues to act? (Assume that the second block does not slide on the first block.)
A 6 kg block sits at rest on a frictionless horizontal table. A 12 N horizontal force is suddenly applied to the block and maintained as the block begins moving. What is the acceleration of the block after the force is applied? What is the speed of the block after it has moved a distance of 0.5 m?
A block of mass m= 15 kg is pulled along a flat surface with a horizontal force F = 135 N. The force of kinetic friction between the mass and the surface is fk = 30 N. What is the acceleration of the block? 9.0 m/s2 7.0 m/s2 4.5 m/s2 2.0 m/s2
A block of mass M is pulled over a rough horizontal surface. The block has a coefficient of kinetic friction with the surface of . The block is subject to the normal force, the friction force, the force of gravity, and a force from a rope of magnitude T which pulls up and to the right at an angle of 0 with the horizontal. The box was initially travelling to the right at speed v = 2.7 m. If M...
1) A block of mass m = 0.52 kg is attached to a spring with
force constant 119 N/m is free to move on a frictionless,
horizontal surface as in the figure below. The block is released
from rest after the spring is stretched a distance A = 0.13 m.
(Indicate the direction with the sign of your answer. Assume that
the positive direction is to the right.)
(a) At that instant, find the force on the block. N
(b)...
A horizontal force, F1=55 N, and a force, F2 = 17.6 N acting at an angle of θ with respect to the x-axis, as shown, are applied to a block of mass m=2.4 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right.Part (a) Solve numerically for the magnitude of the normal force, FN in newtons, that acts on the block if θ = 30°. Part (b) Solve...
