Will mark study the graph shown. it is a graphic of a car trip taken by karen and her mother. the starting position (0,0) is their home. calculate the average speed of the car during the first hour of the trip: 1 miles/hour, 5 miles/hour, 40 miles/hour or 25 miles/hour?

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

What is the final velocity of the initial velocity of 25 and -50?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
