2)A cart is on a horizontal surface and there is no friction between the cart and the surface. Andrew pushes on the cart from the left. For each force acting on the cart, name the two interacting objects and describe the force using the following language with appropriate details provided for the underlined words: “(Object) exerts a (directional), (type of) force on (object).” >> 3)Draw a free body diagram for the cart in the above scenario. >> ...
John is pushing a 50 kg box with a force of 100 N. The maximum static frictional force is 125 N. a) Draw a free body diagram. b) What is the coefficient of friction between the box and ground? Suppose John then pushes the box with Sally on top of it, who is 80 kg. The box comes to a stop and Sally then holds a present of an unknown mass. The maximum static frictional force is found to be...
(Assume the pully and string are massless and there is no friction present.) Determine the acceleration of the 5 kg block? Draw a free body diagram, label and define all forces.
The force is increased until, right after hitting 4N the box starts to move. Draw the Free Body Diagram for the mass right before the mass starts moving. Identify ALL the forces acting on it. 2 Kg 2 Kg i)Determine the magnitude of the normal force n on the box and the value of the coefficient of static friction. Us between the box and the floor.

Since the floor is rough, it exerts both a normal force N, and a frictional force / on the ladder. However, since the wall is frictionless, it exerts only a normal force N on the ladder. The ladder has a length of L-43m aweight of w -67.0 N, adrests against the wall a distance d.3.75 m above the floor. If a p son with amass rm" (a) the forces exerted on the ladder when the person is halfway up the...
Tactics Box 5.1 Working with Friction ForcesLearning Goal:To practice Tactics Box 5.1 Working with friction forces.Although friction is a complicated force, many aspects of it can be described with a simple model. This Tactics Box presents the conditions under which these models are valid and outlines the essential steps in solving friction problems.TACTICS BOX 5.1 Working with friction forces1. If the object is not moving relative to the surface it's in contact with, the friction force is static friction. Draw...
a. Place the crate on top of the ramp with the angle at
20o. Draw a free body diagram showing all the
forces and their components.
b. If the crate does not go down the ramp, which two forces are
responsible for keeping the ramp at rest and preventing it from
sliding down?
c. Slowly increase the angle until the block JUST starts to
move. What is the angle when the block JUST moves?
d. For the angle when the block JUST...
