Blocks a (mass 8.00 kg ) and b (mass 14.00 kg , to the right of a) move on a frictionless, horizontal surface. initially, block b is moving to the left at 0.500 m/s and block a is moving to the right at 2.00 m/s. the blocks are equipped with ideal spring bumpers. the collision is headon, so all motion before and after it is along a straight line. let +x be the direction of the initial motion of a. part afind the maximum energy stored in the spring bumpers. express your answer with the appropriate units. uspringmax u s p r i n g m a x = nothingnothing

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.
