Question

The block of M=5kg, modeled as a particle, rests on the inclined surface that makes an angle of θ with the horizontal ground. The static friction coefficient between the block and the surface is μs=1/3. A force of P is horizontally applied on the block. Take g=10m/s/s for convenience.

1. Draw a free body diagram.

2. Write each force expressed in cartesian vector form.

3. Write down scalar compontent form of equilibrium equations in x and y direction.

4. Find value of p such that the static friction is 0.

5. Find the range of P needed to keep the block at rest.

Answer #1

The block of M=5kg, modeled as a particle, rests on the inclined
surface that makes an angle of θ with the horizontal ground. The
static friction coefficient between the block and the surface is
μs=1/3. A force of P is horizontally applied on the block. Take
g=10m/s/s for convenience.
Angle of slope is 36.87

A 5.00-kg 5.00-kg block is sent up a ramp inclined at an angle
?= 25.0 ∘ θ=25.0∘ from the horizontal. It is given an initial
velocity ? 0 =15.0 m/s v0=15.0 m/s up the ramp. Between the block
and the ramp, the coefficient of kinetic friction is ? k =0.50
μk=0.50 and the coefficient of static friction is ? s =0.60.
μs=0.60. What distance ? D along the ramp's surface does the block
travel before it comes to a stop?

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.

A block of mass m = 3.3 kg is on an inclined plane with
a coefficient of friction μ1 = 0.39, at an
initial height h = 0.53 m above the ground. The plane is
inclined at an angle θ = 44°. The block is then compressed
against a spring a distance Δx = 0.13 m from its
equilibrium point (the spring has a spring constant of
k1 = 35 N/m) and released. At the bottom of the
inclined plane...

An athlete competing in long jump leaves the ground with a speed

a. 4.8 m
b. 3.4 m
c. 10.2 m
d. 5.1 m
