As a 75.0-kg man steps onto a bathroom scale, the spring inside the scale compresses by 0.650 mm. Excited to see that he has lost 2.50 kg since his previous weigh-in, the man jumps 0.300 m straight up into the air and lands directly on the scale. (a) What is the springs maximum compression? (b) If the scale reads in kilograms, what reading does it give when the spring is at its maximum compression?

A spring is compressed by a 0.2 kg marble and held stationary. When released, the spring extends 4 cm (0.04 m) forcing the marble to a velocity of 0.68 m/s. What is the spring constant, k, of the spring? Please show work- i NEED to see how it's being worked out.

A 25-kg child uses a pogo stick to bounce up and down. The spring constant, k, of the toy equals 8750 N/m. a) By how much would the spring be compressed by the child if she simply balanced herself vertically on the pedals of the stick? b) How much energy is stored in the spring under this circumstance?
A spring-loaded toy gun is used to shoot a ball of mass m=1.50kg straight up in the air, as shown in (Figure 1). The spring has spring constant k=667N/m. If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y=0 and then released, the ball reaches a maximum height hmaxℎmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the gun. Assume that all movement occurs in a straight line up and down along the y axis.
