The stone starts with a velocity of 57 feet per second. it leaves the sling at ground level. What is the maximum height that the stone will reach?

Answer 1

equation is y=-16t^2+57t

maximum height is at vertex of this downward facing parabola

x coordinate of the vertex is at -b/2a= -57/-32

y value would be -16(57/32)^2 + 57(57/32)=50.8
