- Given the inclined plane in the diagram, the ball's mass is 5kg. The velocity of the ball at the bottom of the incline is 6.0 m/s. What is the coefficient of friction of the inclined surface?Use the worked example above to help you solve this problem. An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. Suppose the coefficient of kinetic friction between the loaded sled and snow is 0.200. (a) The Eskimo pulls the sled 5.60 m, exerting a force of 1.10 x 102 N at an angle of 0 = 0°. Find the work done on the sled by friction, and the net work. J W fric W net (b) Repeat the calculation if the applied force is exerted at an angle of 0 = 30.0° with the horizontal. W fric W netWhat would the FBD of the basketball at point 1, 2, and 3 look like? Draw 3 seperate FBD for each point. Label the forces and direction. Use a dynamics approach.
- Two boxes are stacked as shown in the diagram below. The bottom box has a mass of 3.5 kg and the top box has amass of 1.5 kg. They are pushed up a ramp inclined at 15° by an applied force of 25 N, applied to the lower boxand directed parallel to the ramp. The coefficient of kinetic friction between the ramp and the bottom box is 0.12.Determine the minimum coefficient of static friction required to keep the top box in place on the bottom box.In this diagram, what direction would the force go in? The textbook says the force goes to the left but shouldn't it go into the paper?Two blocks ( 15 Kg and 25kg) are shown on a 40 degree incline connceted by a rope. An applied force acts on the 15 kg block with a direction parallel to the incline as shown. There is no friction. Assume the applied force is 25 newtons. Calculate the magnitude of the accerlation at the 15kg block on the incline Also calcualte if applied force is 256 newtons
- A bird house of mass 2 kg is supported by two cables ( left horizontal cable tied to the wall and the right cable tied to the wall making an angle of 30 degrees with the horizontal, shown in the figure below. Find the tension in each cable. 30°Find the unknown mass of the block 1 needed to balance the bar. Assume that the mass of the bar is negligible. Block 1 is located 0.85 m left of the center of the bar. Blocks 2 and 3 are located at 0.25 m and 0.50 m right of the center of the bar. The masses of the blocks 2 and 3 are showed. Give the result in the nearest whole number. Do not include units in the result. Hint: the only acting force is the weight. This problem is about torque.
