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...

Why is there a focus on conserving energy resources if the Law of Conservation of Energy states that the amount of energy in a system (i.e. the Universe) remains constant over time? A.) Only Physics students know about the Law of Conservation of Energy. B.) Earth is losing its energy to space and cannot recapture it. C.) The total amount of energy remains constant, but some energy is lost to forms that cannot be used for mechanical work every time...
