The coefficient of friction is 0.14. 1) My Rube Goldberg device The stage I will assess is the concept that I have a wet dog food can weighing 13 oz (368g) set on its side that will be sitting on the edge of two books measuring 3.5 inches (8.89 cm) high. The can is resting against a piece of cardboard holding it in place. Once I move the cardboard, the can will roll down a plastic inclined file folder measuring the same 3.5 inches at its highest point, traveling 11.5 inches across with a 14-degree inclined slope. The first dog food can will hit a second can waiting for it at the bottom of the slope, on a flat surface. A. Initial Velocity: Calculate the initial velocity of the object in the selected step. Explain what the object's initial velocity tells you about the object's behavior. B. Velocity and Force Calculations: Calculate the change in velocity that would be observed based on kinematics and force principles. Then use Newton's Second Law to calculate the force acting on the object.

** Please label the question answers so I could understand it better! Thank you! Scenario: A chair with a mass of 20.0 kg is attached to one end of a frictionless pulley system via a strong massless rope. The other end of the rope is attached to a steel water tank sitting on a flat horizontal concrete surface (see the image to the right). The coefficient of static friction between steel and concrete is 0.45 and the coefficient of kinetic friction between the surfaces is 0.30. The water tank, which is full of water, has sprung a leak. The combined mass of the water and the tank is 500 kg. This mass slowly decreases as the water leaks from the hole. You (i.e. your entire mass) are sitting at rest in the seat. You and the seat will remain at rest as long as the force of static friction is strong enough to hold you. Task: LET [DOWN] and [RIGHT] be positive.
