ID: A18. 2 sA model for the vertical motion of a projected object is given by the equation h = −16t 2 + vt + s, where h is theheight in feet, t is the time in seconds, v is the initial velocity in feet per second, and s is the starting height ofthe object in feet. Use this equation to find the time taken by the rocket to reach the height of 96 feet.19. 2 sA model for the vertical motion of a projected object is given by the equation h = −16t 2 + vt + s, where h is theheight in feet, t is the time in seconds, v is the initial velocity in feet per second, and s is the starting height ofthe object in feet. Use this equation to find the time taken for which the ball remains in the air beforetouching the floor.2
