A block with mass m1 = 7.5 kg rests on the surface of a horizontal table which has a coefficient of static friction of μs = 0.63. This block is connected by a pulley system to another block which hangs vertically. The hanging block has mass m2. a. What is the minimum mass, m2,min, in kilograms, that will cause the system to move? b. A second block with mass of 10 kg is placed on top of the first block. What is the new hanging mass, m2,min', in kilograms, that will cause the system to move? c. The table is inclined at an angle, θ, relative to the horizontal in such a way that the pulley is at the highest point and the 10 kg is removed from m1. Write an equation for the magnitude of the normal force, FN, of the block. d. Write an equation for the tension, T, in terms of mass m1 just before the block begins to slide. Note that the angle θ is not so large that the block would slide down the table under its own weight (i.e. if the tension acting on mass m1 were removed, the block would…

1. A car of mass 500.0 kg has an initial velocity of 10.0 m/s. This car is about to perform a stunt for an upcoming action movie. While traveling on a horizontal road, it accelerates due to a force F=1500 N parallel to the road. 5 seconds later it reaches the edge of a cliff from where it falls for 50.0 m. At that moment the horizontal force stops existing. You can ignore friction in your calculations. a. Draw a sketch of the problem including all the information that is provided. Hint: You must include a reference frame in your drawing! b. Calculate velocity with which the car jumps the cliff. c. Calculate the gravitational potential energy of the car before and after the fall. d. Calculate the kinetic energy of the car before and after the force is exerted. e.
