a) A box that weighs 8.20kg was slid down a platform at an inclination of 45.0o to the horizontal (see figure below). The kinetic friction coefficient is 0.26. The box has a rope connected to it which is coiled around a disc that weighs 9.46kg and is on a fixed axis at O. The disc has a moment of inertia of 0.500kg.m2 with respect to the rotational axis. i) The moment of inertia of the disc is given by ? = 1 2 ?? 2 . Calculate the radius R. ii) Draw a diagram showing the forces acting on the box and the disc. iii) Calculate the acceleration of the box down the platform. iv) What is the tension of the rope?

A cubical box is filled with sand and weighs 578 N. We wish to "roll" the box by pushing horizontally on one of the upper edges. (a) What minimum force is required? (b) What minimum coefficient of static friction between box and floor is required? (c) If there is a more efficient way to roll the box, find the smallest possible force that would have to be applied directly to the box to roll it. (Hint: At the onset of...

A toboggan with two people on it weighs 300 lb. It starts from rest down a slope, 1/4 mile long, from a height 200 ft above horizontal level. The coefficient of sliding friction is 3/100 and the force of the wind resistance is proportional to the square of the velocity. When the velocity is 30 ft/sec, this force is 6 lb. (a) Find the velocity of the toboggan as a function of the distance and of the time. (b) With...

A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. a) Enter an expression for the minimum angle θ (in degrees) the box will begin to slide. b) Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is...

A box (with a penguin inside) with mass, M, slides down a frictionless ramp, starting a height H above ground level. At the lowest point of the ramp (height = -0.1H) it slides through a curved section of track with radius, R= 0.25H. The box (w/ penguin) then rises to ground level (height = 0) and at that point, leaves a jump at an angle θ. At the highest point of its trajectory, h2, it strikes a blob of glue...

A box of physics books slides down a ramp inclined at an angle of 40 degrees to the horizontal. The total length of the ramp is 10m. The coefficient of kinetic friction between the box and the ramp is .2 for the top 8m and zero for the bottom 2m. Upon reaching the bottom of the ramp, a spring bounces the box back upward. (a) Find the distance that the box travels back up the ramp on the return bounce....

A box slides down a frictionless incline and a hoop, uniform disk and a solid sphere all roll down another incline of exactly the same length and height. They all have the same mass and start out from rest at the same time. Rank the objects: box, hoop, disk and sphere in the order they reach the bottom of the ramp. If any reach the bottom at the same time, state that explicitly. Reaches first ______ ______ ______ ______ Reaches bottom last
