a flight attendant pulls on a 50 N flight bag a dsitance of 250m along a level airport floor at a constant speed. a 30 N force is exerted on the bag at an angle of 50 degrees above the horizontal. How much work is done on the flight bag

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.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

What is friction? how does it affect the motion of an object?
