incline01_block1+rope+friction.problem

Block 1 (**20 kg**) is pulled by a rope from
**left to right** up a ramp which is inclined
**50 degrees** from the horizontal. The rope pulls on
block 1 with a force of **300 N** parallel to the
surface of the inclined plane. The **coefficient of kinetic
friction** between the block and the surface equals
**0.1**.

On a sheet of paper, **draw** the free body diagram
for block 1 using the two-subscript notation from class. Assume
that the x-axis is parallel to the incline and positive in the
direction up the incline. After completing the free body diagram,
enter below each force and its x & y-components.

**FORCES on BLOCK 1**

Weight force on block 1 by Earth

**W1E** = __ i + __j N

Tension force on block 1 by Rope

**T1R** = __ i + ___ j N

Normal force on block 1 by Surface

**N1S** = ___ i + ___j N

Frictional force on block 1 by Surface

**f1S** = ___ i + ___j N

What is the acceleration *a* of block 1?

*a* = ___i + ___ j m/s^{2}

A 128 N carton is pulled up a frictionless baggage ramp inclined
at 30.0 ∘ above the horizontal by a rope exerting a 72.0 N pull
parallel to the ramp's surface. If the carton travels 5.20 m along
the surface of the ramp, calculate the work done on it by the rope,
gravity, and the normal force of the ramp.
What is the net work done on the carton?

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...
