Room Volume

A room is 15' long, 12' wide, and 8' high. What is the volume of the room in cubic feet?

Stopping Distance

At 35 mph a car has a stopping distance of about 50 feet. The stopping distance is directly proportional to the kinetic energy of the car, which is proportional to (mv²)/2, where m is the mass of the car and v is its velocity. How many more feet will be required to stop at 40 mph?

Kinetic Energy

A Ford Taurus with an 80-kg driver has a mass of approximately 1732 kg. The kinetic energy of the car and driver can be calculated from the formula E = (mv²)/2, where m is the mass of the car and driver, and v is the velocity. The resultant energy is expressed in joules (J). Find the kinetic energy of the car and driver at 27 m/sec.
