A block with mass m1 = 4.00 kg and a ball with mass m2 = 7.00 kg are connected by a light string that passes over a massless, frictionless pulley, as shown in the figure below.

(b) Check the answer for the acceleration by using the system approach.
A block of mass m = 240 kg rests against a spring with a spring constant of k = 550 N/m on an inclined plane which makes an angle of θ degrees with the horizontal. Assume the spring has been compressed a distance d from its neutral position. Refer to the figure. (a) Set your coordinates to have the x-axis along the surface of the plane, with up the plane as positive, and the y-axis normal to the plane, with out of the plane as positive. Enter an expression for the normal force, FN, that the plane exerts on the block (in the y-direction) in terms of defined quantities and g. (b) Denoting the coefficient of static friction by μs, write an expression for the sum of the forces in the x-direction just before the block begins to slide up the inclined plane. Use defined quantities and g in your expression. (c) Assuming the plane is frictionless, what will the angle of the plane be, in degrees, if the spring is compressed by gravity a distance 0.1 m? (d) Assuming θ = 45 degrees and the…

In the attached Word file, a shape is on an x-y axis, beginning at x = 0. The bottom of the shape is 25 cm long and it reaches a height of 20 cm. The shape weights 450 g.

For the cube from problem 1, instead of having a person push the cube, we are going to attach a spring to it. The box is pulled to compress the spring 50 cm, then released. If the stiffness of the spring is 500 N/m, what acceleration will the cube experience? b. Now, we will move the cube and spring device to a smooth, tile floor, and we will place the cube on wheels. This will lead to some, non-negligible amount of friction. If the coefficient of static friction between the wheels and the floor is 0.07, what acceleration will the cube experience? Replace the single, large cube from the previous problems with two smaller cubes with the masses 5 kg, and 10 kg. Now we're back on the ice. The two cubes are side-by-side. Now a person pushes on box 1 with a force of 50 N at an angle of 30°. What is the acceleration of the boxes?
A small block with mass m is set on the top of an upside-down hemispherical bowl. If the coefficient of static friction between the block and the bowl is μs and the block is slowly repositioned at different points down the surface of the bowl, at what angle measured from the vertical will the block begin to slide? Write your answer in terms of the mass, m; the gravitational acceleration on Earth, g; and the coefficient of static friction, μs. (Assume the +y axis is vertically upward.)
