A rock is released from rest into water. The magnitude of Fd of the drag force acting on the rock due to its motion through water can be modeled as Fd = Cd(v), where v is the speed of the rock and Cd is the constant drag coefficient. Determine the units used to measure Cd in the US Customary System.
What fraction of incident intensity is transmitted by system
how to Calculate the acceleration of the system. Assume the magnitude of the acceleration is the same during starting and stopping.
He would like a prescription for contact lenses to serve the similar purpose. What is the correct contact lens prescription, in diopters.
In the physics lab a metal spring is stretched 10cm vertically downward by a 500 g mass attached to it. How much would the similar spring with the same attach mass stretn themon? The mass of the moon is 7.35 x 10 to the 22kg, gravity is 1.62 m/s a..

A player bounces a 0.47 kg soccer ball off her head, changing the velocity of the ball from i = (9.2 m/s) + (-2.7 m/s) to f = (6.1 m/s) + (5.5 m/s). The ball is in contact with the player's head for 6.70ms.
A girl on a sled coasts down a hill. Her speed is 7.60 m/s when she reaches level ground at the bottom. The coefficient of kinetic friction between sled's runners and the hard, icy snow is 0.04, and the girl and sled together weigh 644N.
A 29 g rifle bullet travelling 270 m/s buries itself in a 3.50 kg pendulum hanging on a 2.6 m long string, which makes pendulum swing upward in an arc. Find out the horizontal component of the pendulum's displacement.
Setting a world record in a 100m race, Maggie and Judy cross the finish line in a dead heat, both taking 10.0 s. Accelerating uniformly, Maggie took 2.0 s and Judy 2.5 s to attain maximum speed that they maintained for the rest of race.
