A student estimated based on the video that the ball left my hand 1.59 meters off the ground, and after 0.59 seconds the ball reached a maximum height. Use this information to find an equation for the height, h of the ball, in meters, after t seconds. Please put in standard form. h = -4.9t2 + 5.78t + 1.59 X Submit
