In a lab investigation, one group of students (group a) measures the speed or a 0.1 kg toy cat w vc212
m/s at the bottom of a ramp. another group of students (group b) measures the speed of the car to be 3
m/s at the bottom of the ramp. the car's starting position at the top of the ramp is 1 m high.
a. what is the potential energy of the car at the beginning of the experiment before its speed is
measured?
