Agolf ball is struck by a 60-degree golf club at an initial velocity of 9898 feet per second. the height of the golf ball in feet is given by the quadratic function h left parenthesis x right parenthesis equals negative startfraction 16 x squared over left parenthesis 49 right parenthesis squared endfraction plus startfraction 84.9 over 49 endfraction xh(x)=− 16x2 (49)2+ 84.9 49x, where x is the horizontal distance of the golf ball from the point of impact. what is the horizontal distance of the golf ball from the point of impact when the ball is at its maximum height? what is the maximum height obtained by the golf ball?
