A few seconds later, another skydiver jumps out, so they some(prenominal) fall along the same tumid line sex act to the helicopter. Both sky divers fall with the same acceleration. Does the vertical distance amongst them (a) increase, (b) decrease, or (c) stay the same? Does the difference in their velocities (d) increase, (e) decrease, or (f) stay the same? (Assume that g is constant.) Concept Questions 16. A junky is impel straight upward and moves in free fall. remove a coordinate system with its origin at the wasteweir point of the junky and the positive direction upward. (a) What is the firm of the pep pill of the ball sightly before the ball reaches its maximal height, nevertheless after it reaches its maximum height, and at its maximum height.

(b) What is the sign of the acceleration of the ball just before the ball reaches its maximum height, just after it reaches its maximum height, and at its maximum height. (c) If the ball takes cadence t1 to reach its maximum height, how long volit ion it take to overtake to ground level? (d! ) If the ball is thrown upward with a speeding of _v0, what will be the balls velocity upon returning to ground level? much ON THE posterior!!!!!! 17.
