A ball is released from a depressed spring as in the diagram shown. Neglecting the 50 cm distance by

. A vertical spring with spring constant 250 N/m and whose mass is negligible is loaded with a 0.050 kg ball and it is compressed by 15 cm when "cocked and loaded", then (a) what speed will it give the ball as it just leaves contact with the spring at the spring's equilibrium position and (b) to what height above the original compressed location will the ball reach when it is launched straight up into the air? Include a diagram of the situation.

A 3.00 kg box that is sliding on frictionless surface with a speed of 15 m/s approaches a horizontal spring. The spring has a spring constant of 1900 N/m. m 10000000 How far will the spring be compressed in stopping the box? Submit Answer Tries 0/10 How far will the spring be compressed when the box's speed is reduced to half of its initial speed? Note: This is not saying that the box starts with half of the original speed, the box still starts with 15 m/s, the question asks how far the spring will have been compressed when it has slowed the box to half of that speed.

A spring-loaded toy gun is used to shoot a ball straight up in the air. (Figure 1)The ball reaches a maximum height H, measured from the equilibrium position of the spring. The same ball is shot straight up a second time from the same gun, but this time the spring is compressed only half as far before firing. How far up does the ball go this time? Neglect friction. Assume that the spring is ideal and that the distance by which the spring is compressed is negligible compared to H.
