Energy changes in a falling object

Web9.81 m/s2. An object initially at rest falls freely near Earth's surface. How long does it take the object to attain a speed of 98 m/s. 10 s. An object starts from rest and falls freely. What is the speed of the object at the end of 3.00 seconds. 29.4 m/s. An object falls freely from rest near the surface of Earth. WebTable 5.2 lists some typical drag coefficients for a variety of objects. Notice that the drag coefficient is a dimensionless quantity. At highway speeds, over 50% of the power of a car is used to overcome air drag. The most fuel-efficient cruising speed is about 70–80 km/h (about 45–50 mi/h).
