It later crashes through the skylight of a cafeteria and lands on top of a table where six fat feminists are eating. The table top is 1 meter from the ground. What is the speed at impact?

When a resistor with resistance r is connected to a 1.50-v flashlight battery, the resistor consumes 0.0625 w of electrical power. (throughout, assume that each battery has negligible internal resistance.) what power does the resistor consume if it is connected to a 12.6-v car battery? assume that r remains constant when the power consumption changes.
