A projectile is launched from the top of a 75m-tall cliff with an initial velocity of 31m/s at an angle of 42° above the horizontal. For this problem, assume that the base of the cliff is at y 0 and that the projectile starts at x 0 on a standard xy plane 1. What is the maximum height above the ground that the projectile will achieve? 2. How long will it take for the projectile to reach its maximum height?...

An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 43.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored. A) What is the initial speed of the egg? Express your answer in meters per second. B)How high does it rise above its starting point? Express...
