35.0 m above the ground. (a) How long does it take the stone to reach the ground? (b) What is the speed of the stone right before it hits the ground? Stone 2 is thrown vertically downward 1.50 s after stone 1 was released. (c) What initial speed should stone 2 have in 0rd ground at the same time? (d) What is the initial speed of stone 2, (e) how long does height that stone 3 can reach? er for both stone 1 and stone 2 to reach the nal speed of stone 2? If stone 3 is thrown upward with the it take stone 3 to reach the ground and (0 what is the maximum 2. A golfer tees off on a platform above the ground, giving ball A an initial speed of 69.0 m/s and an initial direction of 40.0\" above the horizontal. If ball A is in ight for 10.00 sec. how high above the ground is the platform, (b) what is the horizontal displacement of ball A when it lands on the ground, (c) what is the ball A's landing angle, and (d) what is the maximum height that ball A can reach? If next golfer in the group hits ball B at an angle 55.0 above the horizontal and ball B has the same horizontal displacement as ball A. (e) what is the initial speed of ball B, and (t) how long is ball B in ight? (Air resistance can be neglected.)
