ACTIVITY 2: (15 points) Direction: Use the GRESA Method in solving the problem below about kinetic and potential energy. Write your answer on your intermediate pad paper. In a lab investigation, one group of students (group A) measures the speed of a 0.2-kilogram car at 2.5 m/s at the bottom of a hill. Another group of students (group B) measures the speed of the car at 3 m/s at the bottom of the hill. The car's starting position at the top of the hill is 1.5 meter high. 1. What is the potential energy of the car at the beginning of the experiment before its speed is measured?

2. Calculate the kinetic energy of the car for group A using the speed (2.5 m/sec) and mass values above.

3. Calculate the kinetic energy of the car for group B using the speed (3.0 m/sec) and mass values above.
