a box with a mass of m = 3.25 kg on a surface inclined at an angle of 35.0°. The coefficient of static friction between the box and the surface is 0.330. Find the minimum magnitude of the force F (in N), applied to the box in a direction perpendicular to the surface, that will prevent the box from sliding down the surface.

19) A brick on an inclined plane with an angle of 30° to the horizontal has a mass of 3 kg. A horizontal force F with a magnitude of 50 N is applied to the brick, such that a component of that force pushes the brick up the plane. The coefficient of kinetic friction between the brick and the inclined plane is 0.15 М 30 30° a) Use Newton's 2nd law to determine the magnitude of the normal force on...

2. A 5 kg block sits at rest on an inclined ramp which makes an angle of 24 degrees with respect to the horizontal. It is noted that even if the angle 0 is increased the block still does not slip. The coefficient of static friction for the bottom surface of the block and the surface of the ramp is us= 0.56. The magnitude of the frictional force acting on the block must be O 1 O O A. 50...

1. The figure shows a box with mass m1 on a
frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at
angle ?2 (> ?1). The pulley
is frictionless and has
negligible mass and assumes that the setup is on the
surface of the earth.
a) Provide free-body force diagram for both boxes.
b) What is the acceleration in terms of m1,...
A brick of mass m is initially at rest at the highest point of an inclined plane, which has a height of 5.1 m and makes an angle of θ = 17° with respect to the horizontal.
Problem 2: A brick of mass m is initially at rest at the highest point of an inclined plane, which has a height of 5.1 m and makes an angle of θ = 17° with respect to the horizontal. After being released, you perceive it to be traveling at v = 0.45 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the brick and the plane is μp =0.1, and...

A 313-kg crate rests on a surface that is inclined above the horizontal at an angle of 17.0°. A horizontal force (magnitude = 414 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate and the incline?

A 15.0-g coin slides upward on a surface that is inclined at an angle of 12.0° above the horizontal. The coefficient of kinetic friction between the coin and the surface is 0.230; the coefficient of static friction is 0.350. Find the magnitude and direction of the force of friction under the following circumstances. (a) when the coin is sliding ______ N (parallel to the incline, down the incline, or up the incline) b) after it comes to rest. (Note: One method...
