Two cars drive on a straight highway. At time t=0, car 1 passes road marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.00km east of mile marker 0 traveling at 30.0m/s due west. Car 1 is speeding up with an acceleration of magnitude 2.5m/s^2 , and car 2 is slowing down with an acceleration of magnitude -3.2 m/s^2 . a.)write position time equation for both cars let east be the positive direction b.) At what time do the cars pass next to one another?

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

Lacie kicks a football from ground level at a velocity of 13.9 m/s and at an angle of 25.0° to the ground. how long will the ball be in the air before it lands? how far will the football travel before it lands?

Find v1, the speed of the fluid in the left end of the main pipe. express your answer in terms of h1, h2, g, and either a1 and a2 or γ, which is equal to a1a2.
