Access Code (located on the underside of the lid of your lab kit): AC-2F7KTRX
Pre-Lab Questions
1. The force due to a spring is variable and is quantified by F = kx, where k is the spring
constant and x is the displacement. Given the graph of the force versus displacement graph
for a spring in Figure 5, write an equation for the amount of work done by the spring.
Figure 5: Force versus displacement of a spring.
W=∫F= 1/2kx^2
2. Consider the ball example in the introduction when a ball is dropped from 3 meters. After the
ball bounces, it raises to a height of 2 meters. The mass of the ball is 0.5 kg
a. What is the speed of the ball right before the bounce?
V=√2gh = √2(9.8)(3)=7.668 m/s
