Question

A shoe sits on a ramp without moving. As the angle of the ramp is increased, the shoe starts to move. This is because:

A)	the normal force has increased

B)	the coefficient of static friction has decreased

C)	force of gravity on the shoe has increased

D)	the component of the normal force along the ramp has increased

E)	the component of gravity acting along the plane of the ramp has increased

You are trying to move a light fixture into an apartment. There are hooks in the elevator so you hang the fixture on a hook with a chain. You don't want the fixture to touch the walls, so you attach a rope to the side that pulls horizontally as shown, keeping the fixture stationary with respect to the elevator. Note 0 = 35°. Chain Rope Fixture As the elevator ascends vertically, the magnitude of the tension force in the chain from the elevator on the fixture as a function of the vertical position of the elevator, y, is Fa(y) = Foe y/n where Fo = 108 N and y1 = 6.5 m. Work From Chain Using the fixture as your system, if the elevator goes from y = 0 to y = 5.85 m, what is the work done by the tension force in the chain on the fixture? Reminder About Work ........................................... Make Sure to Integrate! Wef = | Work From Rope The tension force in the horizontal rope as a function of y is Ff(y) = Fje-y/y1 where F = 61 N and y1 = 6.5 m. What is the work done by the…
In an old-fashioned amusement park ride, passengers stand inside a 3.90 m diameter hollow steel cylinder with the backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a coefficient of static coefficient of friction against steel in the range of 0.690 to 1.0 and a kinetic coefficient in the range 0.480 to 0.70. A sign next to the entrance says "No children under 30 kg allowed." What is the minimum angular speed in rpm (do not enter units) for which the ride is safe? Assume that the local acceleration due to gravity is -9.80 m/s². Submit Answer Tries 0/10
One of the rides at an amusement park consists of small cars that are supported by steel cables 5.00 m long and rotated in a circle at gradually increasing speed. As the speed increases, the cars rise. Find the speed of a car when the cable makes an angle of 35.0 degrees with the vertical.
Suppose a toy car experiences two horizontal forces: A time-dependent force from its motor of F = 2.0e-0.5tN, and kinetic friction with a coefficient of u = 0.1 from its wheels and bearings. What will its maximum speed be on level ground if it starts from rest? %3D %3D
A constant force Fa pushes a 22.5-kg box across a rough horizontal surface. The magnitude of Fa is 185 N and the force is inclined at an angle of θ = 30.0° below the horizontal. The coefficient of kinetic friction between the box and the surface is μk = 0.500. What is the magnitude of the box's acceleration?
A "swing" ride at a carnival consists of chairs that are swung in a circle by L = 15.8 m cables attached at an angle of θ = 57.4° to a vertical rotating pole, as the drawing below shows. Suppose the total mass of a chair and its occupant is 161 kg. Calculate the tension in the cable attached to the chair.
A crate remains stationary after it has been placed on a ramp inclined at an angle with the horizontal. Which of the following statements must be true about the magnitude of the frictional force that acts on the crate? O It is least equal to the weight of the crate. O It is equal to n. O It is larger than the weight of the crate. O It is greater than the component of the gravitational force acting down the ramp. O It is equal to the component of the gravitational force acting down the ramp.
Consider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false . The normal force is not always parallel to the force of gravity The normal force is independent of the force of gravity The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity The normal force causes an acceleration and therefore does not interact with gravity
Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B is full. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is µs. The speed of the turntable is gradually increased. Describe what will happen. Include which container will fall off first or if they will fall off at the same time.
