You fire a bullet into a 2 kg wooden block that is hanging at the bottom of a pendulum. When
the bullet strikes the block, the pendulum swings upward. The bullet has a mass of 0.02 kg
and strikes the block with a speed of 300 m/s.
a. What is the speed of the block and bullet when they first start moving together?
b. What is the maximum height reached by the pendulum?

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.
