A block of mass m is placed in a smooth-bored spring gun at the bottom of an inclined plane
A block of mass m is placed in a smooth-bored spring gun at the bottom of an inclined plane, such that it compresses the spring by an amount xc, as shown in the figure below. The spring has a spring constant k. The incline makes an angle θ with the horizontal and the coefficient of friction between the block and the inclined plane is μ. The block is released, exits the muzzle of the gun, and slides up the incline...

A 4.40-kg block is set into motion up an inclined plane with an initial speed of Vi = 8.20 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of 0 = 30.0° to the horizontal. (a) For this motion, determine the change in the block's kinetic energy. (b) For this motion, determine the change in potential energy of the block-Earth system. (c) Determine the friction...

In this problem, we will consider the following situation as
depicted in the diagram (Figure 1) : A block of mass
m slides at a speed v along a horizontal, smooth
table. It next slides down a smooth ramp, descending a height
h, and then slides along a horizontal rough floor,
stopping eventually. Assume that the block slides slowly enough so
that it does not lose contact with the...

A block of mass mis attached to a horizontal spring and rests on a flat, smooth surface as seen in the figure. The block can be pushed in the negative x- direction to compress the spring or pulled in the positive x-direction to stretch the spring. Where along the x-axis does the block have to be for the spring to have zero potential energy? Marked out of Flag estion ix=0 0 Select one: O a. The spring has zero potential...
