![3(c) [7 Marks] A golf ball is struck with velocityv (meters per second) from the edge of a cliff which rises h metres above sea level. Referring to figure (3) the golf ball starts at the point (0, h) follows a parabola and strikes the sea some time later at the point (8,0). It can be shown that the (x, y) location of the ball is a function of time where the individual components satisfy r(t)vt where g is the acceleration due to gravity (9.8 metres per second per second) Derive an expression for t, the time the ball strikes the sea surface. From this derive an expression for s in terms of g, h and v. At what time te is the ball as far horizontally from the cliff as it is vertically above the sea?](http://img.homeworklib.com/questions/a5e69040-427c-11ea-b39f-7f148992f4ac.png?x-oss-process=image/resize,w_560)
