A person pushes on a 91.2 kg refrigerator with a horizontal force.  The coefficient of static friction is 0.593. What is the magnitude of the largest pushing force that can be applied to the refrigerator before it just begins to move?

A 10 kg box experiences a force of 15 Newtons in the positive x-direction and 8 Newtons in the negative y-direction. What is the magnitude of the net force acting on the box? Answer in Newtons.

In the figure here, a box of Cheerios (mass mc = 1.70 kg) and a box of Wheaties (mass mw = 2.60 kg) are accelerated across a horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.10 N, and the magnitude of the frictional force on the Wheaties box is 4.60 N. If the magnitude of F is 12.7 N, what is the magnitude of the force on the Wheaties box from the Cheerios box? Number i Unit

A 32 kg child puts a 15 kg box into a 12 kg wagon. The child then pulls horizontally on the wagon with a force of 65 N. If the box does not move relative to the wagon, what is the static friction force on the box?

In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?

A wooden box of mass 30 kg slides on a concrete floor. What is the coefficient of friction if the frictional force acting between the box and the surface is 180 N? 0.061 0.312 0.031 O 0.612

You want to push a 22.0 kg rock up a 42.0° hill. You do so by pushing the rock with a 432.0 N horizontal force. The coefficient of kinetic friction between the rock and the hill is 0.125. What is the acceleration of the rock up the hill? What's the normal force from the hill on the rock?

Two forces are acting on a 0.150 kg hockey puck as it slides along the ice. The first force has a magnitude of 0.320 N and points 35.0° north of east. The second force has a magnitude of 0.520 N and points 65.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east.  magnitude of acceleration:               m/s2   direction of acceleration:        °

A large cube (mass = M) being accelerated across a horizontal frictionless surface by a horizontal force . A small cube (mass = m) is in contact with the front surface of the large cube and will slide downward unless is sufficiently large. The coefficient of static friction between the cubes is u. What is the smallest magnitude that F can have in order to keep the small cube from sliding downward?
