You've Gotta Break Some Egs (Gravitational Potential Energy Practice) NAME: Please show all your work, including any relevant diagrams 1. How high does a 0.3 kg stone need to be lifted from Earth's surface to gain 3000 J of gravitational potential energy? 2. Some astronauts a small asteroid perform the same experiment as your lab using a 2 kg cart. Their data are represented by the trendline shown on the graph below. What is the value of the gravitational field on this asteroid? Gravitational Potential Energy vs. release height of cart on unknown asteroid A Gravitational Potential Energy (J) w N 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 Release Height (m)
