A 5.0 kg chair sits on a ramp which is at an angle of 10^0 with respect to the horizontal. A boy wants to push the chair up the ramp. The coefficient friction between the chair and the floor is (0.3, 0.2) Draw a free-body diagram. Does the boy need to push on the chair to keep it from sliding down the incline? (Be sure to show your work.) If the chair is at rest, then what is the maximum...

Draw a free-body diagram for a 70-kg person standing in an elevator carrying a 15-kg backpack (do not consider the backpack a part of the person!). (a) if the elevator is not moving, and (b) if the elevator is accelerating downwards at 2m/s2. In each case, what is the magnitude of the normal force exerted on the person by the floor?

Block A of mass 10 kg sits on top of Block B of mass 15 kg. Block B is being tugged by a force F and Block A is being tugged by a force FA . FA makes an angle ? = 10degrees with the horizontal and is a 7N force. The coefficient of static friction between the two blocks is .01while the coefficient of kinetic friction between the floor and Block B is given as .5(see diagram below). Force...

A child sits on a merry-go-round at a distance of 3.0 m from its axis of rotation. The coefficient of static friction between the child and the surface of the merry-go-round is 0.6. Find the largest angular velocity (in rpm) the merry-go-round can have before the child starts to slide outward. Your solution must show a free-body diagram of the child.
Whenever you face a problem involving forces, always start with a free-body diagram.
Learning Goal: To gain practice drawing free-body diagramsWhenever you face a problem involving forces, always start with a free-body diagram.To draw a free-body diagram use the following steps:Isolate the object of interest. It is customary to represent the object of interest as a point in your diagram.Identify all the forces acting on the object and their directions. Do not include forces acting on other objects in the problem. Also, do not include quantities, such as velocities and accelerations, that do...
