By what factor does the drag force on a car increase as its velocity increases from 65.0 km/h to 110 km/h?
A skydiver with a mass of 80.0 kg falls through air that has a uniform density of 1.23 kg/m3. The skydiver has a surface area of 0.140 m2 and a drag coefficient of 0.690. What is the skydiver’s terminal velocity?
A boater and motor boat are at rest on a lake. Together, they have mass kg. The thrust of the motor provides a constant force on the boat of 40 N in the direction of the boat’s motion. If the value of resistive force of the water in Newtons is two times the value of the speed of the boat in m/s, find the limiting speed of the boat.
