A 37 kg runaway shopping cart is rolling toward Elon’s shiny new tesla at 4.5 m/s. If he exerts a 70 N force to stop the cart, how much distance will the cart roll while it is being stopped?

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.

Give an example in which the electrical energy changes to light energy
