A55kg female bungee jumper fastens one end of the cord (made of elastic material) to her ankle and the other end to a bridge. then she jumps off the bridge. as the cord is stretching it exerts an elastic force directed up on her. calculate her acceleration at the instant the chord exerts an elastic force of 825n [up] on her.

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.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

What are the three ways that an object can accelerate
