How are potential energy, kinetic energy, and total energy related?

A mass of 5 kg stretches a spring 10 cm. The mass is acted on by an external force of 10 sin (t/2) N (newtons) and moves in a medium that imparts a viscous force of 2 N when the speed of the mass is 4 cm/s.

Which has greater kinetic energy, a car traveling at 30 km/HR or a car of half the mass traveling at 60 km/HR? a. The 60 km/HR carb. The 30 km/HR carc. Both have the same kinetic energyd. More information is needed about the distance traveled
