A590 g squirrel with a surface area of 920 cm2 falls from a 4.0-m tree to the ground. estimate its terminal velocity. (use the drag coefficient for a horizontal skydiver. assume that the squirrel can be approximated as a rectanglar prism with cross-sectional area of width 11.5 cm and length 23 cm. note, the squirrel may not reach terminal velocity by the time it hits the ground. give the squirrel's terminal velocity, not it's velocity as it hits the ground.) m/s

What is work? how much work is done to move an object 0 meters?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?
