He shoots the tree stump, which has a mass of (m), with a bullet of mass (m) traveling at some velocity (vbullet), and the bullet lodges itself inside the tree stump before the system of objects slides along the ice. what is the speed of the tree stump-bullet system immediately after the collision?

What is the relationship between the wavelength of a wave and it's energy?

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
