Name: Jen Bazzell Date: 12/21/2015 Instructor’s Name: Prof. Jantz Assignment: SCI103 Phase 5 Lab Report TITLE: Potential and Kinetic Energy INSTRUCTIONS: Enter the Virtual Lab and conduct the experiments provided. Please type your answers on this form. When your lab report is complete, submit it to the Submitted Assignments area of the Virtual Classroom. Part I – Answer the following questions while in the Phase 5 lab environment. Section 1 – From the left of the screen to the right, the red balls have a center of mass placed at 20 feet, 15 feet, and 10 feet high respectively. 1. Suppose each red ball weighs 20 lbs. Find the potential energy (PE) for each ball on each ramp. In this lab mass is given in pounds and height is in feet, so use 32.2 ft/sec 2 as the gravitational constant . Your answer will be in foot- pounds since US units are being used. PE = m g h where g = 32.2 ft/sec 2 Ramp 1: 12880 foot-pounds Ramp 2: 7728 foot-pounds Ramp 3: 3542 foot-pounds 2. Predict the maximum speed (velocity) of each ball on each ramp. How would this speed change if each ball’s mass was doubled? ASSUMPTION: assume

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
