In a lab investigation. one group of students (group a) measures the speed of a 0.1-kilogram car at 2.5 m/sec at the bottom of a hill. another group of students (group b) measures the speed of the car at 3 m/sec at the bottom of the hill. the car's starting position at the top of the hill is one-meter high. what is the potential energy of the car at the beginning of the experiment before its speed is measured?
Answers: 1
is the mass of the car, 
is the gravitational acceleration and 
is the height of the hill. Using these data, we have

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
