a. Draw a free-body diagram of the situation.

b. Find the work done by the 12 N force on the block to move the block 3m?

c. Find the work done by the force of friction on the block when the block was moved 3m?

Answer #1

**If you have any doubt, feel free to discuss in the
comments.**

A 6.53-kg block initially at rest is pulled to the right along a
horizontal surface by a constant force of 125 N applied at an angle
θ above the horizontal. The coefficient of kinetic friction between
the block and the horizontal surface is 0.150. At what angle θ
above the horizontal surface should the force be applied to achieve
the largest possible speed after the block has moved 5.00 m to the
right?

An 8.0 kg block initially at rest is pulled to the right by a 12
N force on a horizontal surface. If there is a constant friction
force of 4.0 N, calculate the speed of the block after it has moved
3.0 m.

horizontal surface, and is attached to an initially unstreteched
spring with a force constant of 2.00N/m2.00N/m. The coefficient of
kinetic friction between the block and the surface is 0.4000.400. A
constant force of 2.30N2.30N to the right is applied to the
block.

A mass m = 12 kg is pulled along a horizontal floor with NO
friction for a distance d =7.2 m. Then the mass is pulled up an
incline that makes an angle θ = 30° with the horizontal and has a
coefficient of kinetic friction μk = 0.49. The entire
time the massless rope used to pull the block is pulled parallel to
the incline at an angle of θ = 30° (thus on the incline it is
parallel...

A mass m = 13 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.07, for a
distance d = 5.1 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 33° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 33°

A box, initially at rest, is pulled by a rope as it slides along
a horizontal (level) carpeted floor in the positive direction;
there is friction. The mass of the box is 8 kg and the tension in
the rope has a magnitude of 40 N. After 4 seconds of pulling, the
box has a speed of 12 m/s.
1. While the box is being pulled:
a. what is the magnitude of acceleration of the box? Answer:
_________
b. what...

A 12 kg block is pulled along a level plane by a F = 76 N force
directed 40° above the horizontal. The coefficient of kinetic
friction between the block and plane is 0.39. Find the x-component
of the 76 N force acting on the block. Find the y-component of the
76 N force acting on the block. Find the normal force acting on the
block. Find the friction force acting on the block. Find the
acceleration of the block.

An 8.5-kg block is pushed along a horizontal rough surface by a
40-N force inclined at 20° with the horizontal. The coefficient of
friction between the surface and block is 0.35. If the block has an
initial velocity of 3.6 m/s and the force does 200 J of work on the
block, find:
(a) The total distance moved by the block.
(b) The final velocity of the block.
