By what factor does the drag force on a car increase as its velocity increases from 65.0 km/h to 110 km/h?
The terminal velocity of a 48.7-kg-mass skydiver is 55.5 m/s. Assuming that drag force can be approximated by , find .
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 are of 0.140 m2 and a drag coefficient of 0.690. What is the skydiver’s terminal velocity?
