In 1991, four english teenagers built an electric car that could attain a speed of 30 m/s. Suppose this car accelerates from 5 m/s to 25 m/s and travels 48 meters. What is the magnitude of the cars acceleration?

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.

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

Observations show that interstellar clouds can have almost any shape and
