10 Pоints A tоy gun uses а spring with а fоrce constаnt of 300 N/m to propel a 10.0-g steel ball. If the spring is compressed 7.00 cm and friction is negligible: How much force is needed to compress the spring? To what maximum height can the ball be shot? The gun is fired from a height of 1.25 meters above the ground, at an angle of 37° from the horizontal. What is the final velocity of the ball as it hits the ground?
