The stories of a tall building are uniformly 10.0 feet in height. A ball A is dropped from the rooftop position shown. Determine the times required for it to pass the 10.0 feet of the first, tenth, and one-hundredth stories (counted from the top). Include the effects of aerodynamic drag. The drag force causes an acceleration component in ft/sec2 of 0.005v2 in the direction opposite the velocity vector, where v is in ft/sec 10.0 A first floor t = sec...

P. The horizontal distance of a projectile (in feet) is given by x (vo cos e)t, and the height of the projectile is given by y = -16t2 + (vo sin 0)t + yo where vo is the initial velocity, e is the angle of inclination, and yo is the initial height. Suppose an object is propelled upward from the ground at an angle e to the horizontal with an initial velocity of vo ft/sec. a. Find a formula for...
