Question

The 50-kg crate is resting on an inclined plane 15 deg. with respect to the horizontal. The coefficient of static friction is 0.2 and coefficient of kinetic friction is 0.15. If a force P, acting upward and parallel to the inclined plane is applied to the crate, determine the resulting acceleration of the crate if P=150N.

Answer #1

A construction worker pushes on a 10 kg crate down an inclined
plane that is 7.0 m long and is inclined at an angle of 20 degrees
to the horizontal. As a result, the crate slides down the entire
length of the plane with a constant speed of 3.0 m/s. Suppose that
the worker pushes directly on the crate in a direction parallel to
the incline with a force of 50 N for the entire length of the
plane. A)...

2. A block slides down a plane inclined at 35o with
respect to the horizontal, with coefficient of kinetic friction
0.2. Find the ratio of the time taken to slide down the plane
starting from rest, compared to the time it would take to slide
down the plane if it were frictionless.
3. A 20 kg block slides frictionlessly down an inclined plane
that is 2.8 m long and 1.2 m high. A person pushes up against the
block, parallel...

If P = 404 N, and the coefficient of kinetic friction between
the 50-kg crate and the inclined plane is 0.25, determine the
crate's acceleration in . Calculate to two decimal places without
the unit.

A block of mass m = 14.5 kg rests on an inclined plane

3-A 1.0 kg block slides down an inclined plane of 39
0 from the horizontal. If the
block starts from rest and hits the bottom in 5.1 s,
what is the speed of the block, in the unit m/s, at the bottom of
the incline? Assume a frictionless plane.
4-A bus negotiates a turn of radius 103 m while traveling at a

Static and Kinetic Friction
A 25 kg crate is placed on a concrete surface. If the coefficient
of static friction is 0.60, how much horizontal force is needed to
push the crate from rest? If it takes a horizontal force of 78 N to
keep the crate moving at constant velocity, what is the coefficient
of kinetic friction?

A 10 kg box was lying on a smooth surface. A
rope was connected to the box. The box was pulled by the rope at
angle of 30° with the
horizontal. What applied force will keep the box
moving upward at a constant speed?
A 10 kg box was resting on an inclined rough
surface, which makes an angle of
30° with the horizontal. The
coefficient of kinetic friction between the surface and the box is
0.4. The box was...

The 5 kg block is receiving a horizontal force of 50 N on the inclined side. The angle between the block and the slope is 30 degrees and the static friction coefficient is 0.3. (1) When the block goes up, what is the acceleration? (2) If the initial speed of the block was 4m/s upward, to what height can the block go up? (3) What happens after the block goes up to its highest height?

A block of mass M2 = 8.45 kg on a plane inclined moving down at
angle θ = 50° is
connected by a cord over a massless, frictionless pulley to a
second block of mass M1 = 5.36 kg
on a horizontal surface. The coefficient of kinetic friction
between M1, M2 and the surface is μk
= 0.150, the Force F1 = 11.3 N is acting downward on M1, and the
Force F2 = 21.8 N is acting on
M2...
