Please help I’ve been stuck on this for a while!
Todd purchased a jumper for his infant son. The jumper clamps to the top of a door frame and has a spring from
which the body of the jumper hangs to allow the infant to jump up and down. Included with the jumper are small
weights, each identical in
weight and size. The weights allow the user to adjust the initial height of the jumper by
stretching the spring a certain distance. Todd adds 8 of the weights and notes the spring stretches 2 centimeters.
a. According to Hook's Law, the amount that a spring is stretched, s, varies directly with the force applied to the
spring by the weights, F. Write an equation that relates F and s for the spring on the jumper
b. Using your equation from part a, find the stretch in the spring if Todd applies 14 of the included weights to the
spring
c. Using your equation from part a find the number of weights necessary for the spring to stretch 7 centimeters.
