Question: A 6.1 kg penguin is sliding on a frictionless horizontal surface with an initial speed of 7.1 m/s. A varying magnitude force is applied in the direction of the motion. The force starts at 23.4 N and decreases at a constant rate so that the force is 9.0 N after 12 seconds. What is the penguin's speed after 8.3 seconds?
The orbital period of Halley's Comet is calculated to be 75.5 years. Many other comets have orbits that extend much farther from the sun, and hence have much longer periods. At aphelion, a typical long-period comet is about from the sun; at perih..
