Question details

The device below is called a Pendulum Impact tester and is used to apply loads in a front- on or side-on orientation to a crash test dummy to calibrate the sensors in the dummy CA similar test is also performed on cadavers to examine how strong different parts of the body are). 1.3 m Figure 1.A Pendulum lmpact Tester During the impact test, the pendulum is dropped from an initial height (called the drop height and it takes the trajectory shown in the figure before hitting the dummy. What is the potential energy ofthe pendulum before release if the mass of the pendulum is 9 kg and the drop height is 1.3m? If energy is conserved, what is the kinetic energy of the pendulum just before impact?
