Draw an FBD for the following mass being pulled up the ramp:

A crate starts from rest and slides 8.05 m down a ramp. When it reaches the bottom it is traveling at a speed of 5.55 m/s. If the ramp makes an angle of 23.0o with the horizontal, what is the coefficient of friction between the crate and the ramp?

Paul is pushing the couch up the ramp into the moving truck at a constant velocity. If he pushes with a force of 241 N directly to the right (NOT AT ANY ANGLE), what is the coefficient of kinetic friction? The mass of the couch is 36.3 kg, and the angle of the ramp is 21.5*.

A 945.0kg car traveling rightward at 22.6 m/s slams on the brakes and skids to a stop (with locked wheels). If the coefficient of friction between tires and road is 0.9710, determine the force of friction. Use correct number of significant figures in answer Force =

A sled is on a horizontal surface and a rope with tension T is pulling on it at an angle e above the horizontal. The sled had mass M and does not move due to the frictional force. In this case the coefficient of friction is ug. In terms of the variables given and g, what is the magnitude of the frictional force in this case? Select one: O a. Tcose O b. H, Mgsin0 Ос. Tsin® O d.

A student pushes a 20kg desk across the floor to the right with a force of 400 N. The coefficient of kinetic friction between the floor and the desk is equal to 0.21.  Calculate the acceleration of the desk.

(Questions 16-18) A 25 kg box is at the bottom of a frictionless incline that is 7 m long as shown and makes an angle of 20 degrees with the horizontal. A person applies a constant horizontal (NOT parallel to the incline, but horizontal) force to the box, starting from rest. It reaches the top of the ramp in 13 seconds. 16. Draw a free-body diagram of this situation showing all forces on the box. 17. What was the magnitude of the box's acceleration during this process? 18. What was the magnitude of the force applied by the person?

For a short period of time, the frictional driving force acting on the wheels of the 2.3-Mg van is FD = (600+2) N, where t is in seconds.

Two blocks connected by a string are pulled across ahorizontal surface by a force applied to one of the blocks,as shown below. The coefficient of kinetic friction betweenthe blocks and the surface is 0.25. If each block has anacceleration of 2.0 m/s2 to the right, what is the magnitude F of the applied force?
