3. A 2-kg box is pushed against a wall with a force of 24 N, directed as shown. The coefficient of kinetic friction between the box and the wall is 0.1. The box is sliding down the wall. a) What is the normal force on the box? (It is not the same as the weight.) b) What is the force of friction between the box and the wall? c) Draw a force diagram for the box. In a separate diagram show the vertical forces only on the box. d) What is the net force on the box? e) What is the acceleration of the box? 3. b) 2.08 N c) 5.52 N d) 2.76 m/s2 30°

James pulls a 1.8 kg dynamics cart up a ramp that is inclined 25o to the horizontal. The cart is initially at rest but is then pulled up the ramp with a force sensor attached to James. The force sensor exerts a force on the cart parallel to the ramp. Negligible friction acts on the cart. What force is required for James to pull the cart up the ramp at an acceleration of 2.5 m/s2?

Migo exerts a horizontal force on a 2 kg box located on an inclined plane with an angle of θ= 37 degrees. The coefficient of static and kinetic friction between the box with an inclined plane is μs = 0.4 and μk = 0.2, respectively. A. What is the minimum force for the box to move exactly B. What is the maximum force for the box to move exactly C. If the box is falling at an acceleration of 0.5 m/s^2, what is the force applied

A block of mass M=8.2 kg placed on a table is pulled to the right by a rope with tension T=40.0 N as in Figure 5. Calculate the minimum coecient of static friction to keep the object at rest.
