A 4.25 kg block is projected at 5.40 m/s up a plane that is inclined at 30.0° with the horizontal. The block slides some distance up the incline, stops turns around and slides back down to the bottom. When it reaches the bottom of the incline again, it is traveling with a speed of 3.80 m/s. If the coefficient of kinetic friction between the block and the plane is 0.500, how far up the incline did the block slide?
Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object 1 has mass 4.60m, object 2 has mass 2.21m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an algebraic expression. Each algebraic expression is given using some combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient. (Example: If the answer is 1.23mgd, just enter 1.23) This potential energy was calculated relative to the bottom of the stairs. If you were to redefine the reference height such that the total potential energy of the system became zero, how high…
A 61.9-kg circus performer is fired from a cannon that is elevated at an angle of 57.3 ° above the horizontal. The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 2.35 m from their unstrained length. At the point where the performer flies free of the bands, his height above the floor is the same as that of the net into which he is shot. He takes 3.02 s to travel the horizontal distance of 28.7 m between this point and the net. Ignore friction and air resistance and determine the effective spring constant of the firing mechanism.

A 68.3-kg circus performer is fired from a cannon that is elevated at an angle of 52.6° above the horizontal. The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 2.00 m from their unstrained length. At the point where the performer flies free of the bands, his height above the floor is the same as that of the net into which he is shot. He takes 2.38 s to travel the horizontal distance of 21.3 m between this point and the net. Ignore friction and air resistance and determine the effective spring constant of the firing mechanism.

A mass of 0.21 kg is initially at rest on a hor- izontal surface. A force, given by F⃗ = Fx ˆı, acts on the mass. The horizontal component Fx is plotted below as a function of position along the x-axes. The coefficient of kinetic friction is 0.044. The acceleration of gravity is 9.8 m/s2 . Calculate the kinetic energy K of the mass as it reaches 5 m. Answer in units of J.
