On the way to your friend’s house, you run out of gas and try to push your 1,350kg car to the gas station. You give the car your best push and it accelerates 1m/s2. Calculate the force you applied to your car. Be sure to show all math work and include units.

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.
