As shown in Figure, a stone is thrown vertically into the air from the top of tower 100 ft. high. At the same instant, a second stone is thrown upward from the ground. The initial velocity of first stone is 50 ft/sec and that of second stone is 75 ft/sec. When and where vill the stones be at the same height from the ground? Sa = ? Vi.=50 ft/sec Sb = ? 100.0 ft Tower Vis=75 ft/sec
