PROBLEM 2 (5 points). Momentum and Mechanical Energy conservation A rifle bullet with mass 150 g strikes and embeds itself in a block with mass 1000 g that rests on a frictionless, horizontal surface and is attached to a coil spring. The initial velocity of the bullet was 700 m/s. The impact compresses the springy a distance x. The spring constant is 550 N/m. The spring is ideal. a) Find the magnitude of the block's velocity (with the bullet stuck...

A 0.500 kg block rests (at x = 0) on a horizontal, frictionless surface as in the figure. The block is pressed back against a spring having a constant of k = 625 N/m, compressing the spring to xi = - 10.0 cm. Then the block is released, and it travels a distance d up an incline with ? = 300 from the horizontal. (10 points) a)What is the potential energy when the spring is fully compressed? b)What is the...
