A person is pulling a block up a ramp with a string. If instead the tension in the string was 44.3 N, and the block's mass was 12.3 kg, then find the work done by the tensional force acting on the block if the block went up the ramp by 0.6 m instead. Assume that the ramp is at an angle of 35.6 degrees from the horizontal instead.
Two blocks are connected by a lightweight string passing over a pulley, as shown in the figure below. The block with mass m1 = 16.5 kg on the incline plane accelerates up the plane with negligible friction. The block's acceleration is a = 1.40 m/s2, and the tension in the segment of string attached to this block is T1. The hanging block has a mass of m2 = 23.5 kg, and the tension in the string attached to it is T2....
2. A block of mass 15.0 kg is
being pulled up a flat incline of angle 30.0? and coefficient of

Two blocks are connected by a lightweight string passing over a
pulley, as shown in the figure below. The block with mass
m1 = 16.5 kg on the incline plane accelerates
up the plane with negligible friction. The block's acceleration is
a = 1.80 m/s2, and the tension in the segment
of string attached to this block is T1. The
hanging block has a mass of m2 = 22.5 kg, and
the tension in the string attached to it is...
A 2.0 kg block is pushed 2.0 m at a constant velocity up a vertical wall by a constant force applied at an angle of 25.0 with the horizontal, as shown in the figure. The acceleration of gravity is 9.81 m/s2.Drawing not to scale. If the coefficient of kinetic friction between the block and the wall is 0.40, find a) the work done by the force on the block. Answer in units of J b) the work done by gravity on the block....
An 8 kg block and a 2 kg block are attached by a string as shown. A 40 N horizontal tension force pulls on the 8 kg block and the string connecting the blocks remains taut while they slide to the right. The surface below is horizontal and frictionless and the strings have negligible mass. Find the magnitude of the tension force that the 8 kg block pulls on the 2 kg block with (the tension in the connecting string).
A block is pulled along a rough horizontal surface by force of
magnitude 100 Newtons, at an angle of 30 degrees as shown. The
block has a mass M=20.0 kg, and the coefficient of kinetic friction
between the block and the surface is 0.50.
a)The horizontal component of the tension, T, is

A 2.74 kg block is pushed 1.41 m up a vertical wall with a
constant speed by a constant force of magnitude F applied at an
angle of 66.3 with the horizontal. The acceleration of gravity is
9.8 m/s2. If the coefficient of kinetic friction between the block
and wall 0.415, find the work done by F.

In the system shown below, there is a block of mass M = 3.6 kg resting on a horizontal ledge. The coefficient of kinetic friction between the ledge and the block is 0.25. The block is attached to a string that passes over a pulley, and the other end of the string is attached to a hanging block of mass m = 2.2 kg. The pulley is a uniform disk of radius 7.9 cm and mass 0.66 kg. Find the...

12. A 3.20 kg block is attached to a light and firm string and is placed on top of a horizontal platform. A horizontal force F-45.0 N is pulling the block to the right. The coefficient of the kinetic friction between the block and the platform is 0.240. The other end of the string is connected to a block of mass 2.80 kg that is hanging straight down as shown in the figure below. The blocks are...
