A target with mass m=3.5 kg is attached to a spring constant k=200 N/m on a horizontal, frictionless surface. The target is struck by a bullet with mass of 20 g, traveling at a speed of v=550 m/s. Bullet embeds itself completely into target. Assuming that the target is initally at rest, what is maximum displacement of the tagret fromthe spring equilbrium position after collision? Assume instant collision occurs. What percent of initial kinetic energy converted to non-mechanical forms of...

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m.
A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...
