Question

For the ideal inclined plane shown (greased with good Spanish olive oil so it’s frictionless) with mass M1 on it.

- Draw the free-body (force) diagram for M1 (include axis).
- Solve for a formula for the acceleration of the mass M1.
- If M1 = 5kg and Ɵ = 30, what is the acceleration of M1?
- If the mass starts at the top and L – 10m, what is the speed as it reaches the bottom of the inclined plane?
- What will it’s kinetic energy be?

Answer #1

As diagram is not provided, I have assumed that length L is of the slope.

If L is the length of height, then substitute then substitute 10 by 20 in part (e) , or drop a comment , I'll rectify it.

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...

A frictionless plane is 10.0 m long and inclined at 42.0°. A
sled starts at the bottom with an initial speed of 4.60 m/s up the
incline. When the sled reaches the point at which it momentarily
stops, a second sled is released from the top of the incline with
an initial speed vi. Both sleds reach the
bottom of the incline at the same moment.

A 9.31 kg block is placed at the top of a frictionless inclined
plane angled at 14.9 degrees relative to the horizontal. When
released (from rest), the block slides down the full 2.77 meter
length of the incline. Calculate the speed (magnitude of the
velocity) of the block at the bottom of the incline. [Start by
drawing a free-body diagram for the block.] Note that all the
information provided may not be necessary to solve the problem.

A block of mass m1 = 3.27 kg on a frictionless plane inclined at
angle θ = 26.2° is connected by a cord over a massless,
frictionless pulley to a second block of mass m2 = 2.60 kg hanging
vertically (see the figure). (a) What is the acceleration of the
hanging block (choose the positive direction down)? (b) What is the
tension in the cord?

1a. a box of dirty money (mass m1
= 3.5 kg) on a frictionless plane inclined at angle θ1 =
37°. The box is connected via a cord of negligible mass to a box of
laundered money (mass m2 = 1.3 kg) on a
frictionless plane inclined at angle θ2 = 54°. The
pulley is frictionless and has negligible mass. What is the tension
in the cord?
1b. three blocks attached by cords that loop over frictionless
pulleys. Block B lies...

A box with mass m = 1.2kg on an inclined frictionless surface is
released from rest from a height h = 1.35 m . After
reaching the bottom of the incline the box slides with friction
(μk=0.2) along a horizontal surface until coming to a rest after a
distance d.
1. Draw a free body diagram for the box while it is on the
incline. Clearly label all forces with standard names.
2. Draw a free body diagram for the...

A solid cylinder starts rolling without slipping from
the top of an inclined plane. The cylinder starts moving from rest
at a vertical height 10m. The mass of the cylinder is 1kg and its
radius is .5m. The moment of inertia of the cylinder is 1/2
mr2 (where m is the mass of the cylinder and r is its
radius).
What is the speed of the center of mass of the
cylinder when its vertical height is 4 mm ?...

As shown in Figure 1, a block (mass: 2.4 kg) is initially at
rest near the top of an inclined plane, oriented at a 25° angle
above the horizontal. The coefficients of static and kinetic
friction along the incline are 0.2 and 0.1, respectively.
(a) Just after the block is released from rest, draw a free-body
diagram for it. (Assume that the block is moving after being
released from rest.)
(b) Determine the magnitude of the normal force acting on...

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...
