A box of weight w=2.0N accelerates down a rough plane that is inclined at an angle ϕ=30∘ above the horizontal, as shown (Figure 6) . The normal force acting on the box has a magnitude n=1.7N, the coefficient of kinetic friction between the box and the plane is μk=0.30, and the displacement d⃗ of the box is 1.8 m down the inclined plane. What is the work Wfk done on the box by the force of kinetic friction?
Figure 4: Top view of force table. (3) Figure 5 is an inclined-plane system that will be stud- ied in the first part of this experiment. As labelled in the figure, the x (y) direction is parallel (perpendicular) to the inclined plane, and the gravitational acceleration is downward. If the hanging mass m is too small, the block mass M on the inclined plane slides down. When the hanging mass is gradually increased to a lower-bound value mi such that...
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 box of m = 50 kg is on an inclined plane with θ = 22 degrees. You are exerting a force of 100 N parallel to the plane and up the plane as shown. If the box is at rest and the coefficient of static friction between the box and the surface of the plane is 0.4, what is the force due to static friction on the box? 182 N 84 N 284 N 100 N OON

A block is at rest on an inclined plane (shown in diagram). Coefficients of friction are μ-02, μ,-0.17. Gravity is 9.8 m/s2 Okg What is the normal force on the box? Let's assume friction were not a factor-the box would slide down the ramp. What is the magnitude of the force that causes the box to24 down the ramp? What is the static friction force on the box? Will the box slide without being pushed down the ramp? What is...
Suppose that a box is being towed up an inclined plane as shown in the figure. Find the force w needed to make the component of the force parallel to the inclined plane equal to 2.7 lb. The force w is about lb. (Round to the nearest hundredth as needed.)
rni 0 A block of mass m1- 21.9 kg is at rest on a plane inclined at 28.0 above the horizontal. The block is connected via a rope and mass less pulley system to another block of mass m2-24.1 kg, as shown in the figure. The coefficient kinetic friction between block 1 and the inclined plane is μ,-0.15. If the blocks are released from rest, what is the acceleration of m2? what is a tension force T on the rope?
