Question
G)Nicholas throws a ball into the air with an initial upward velocity of 80 ft/see. As the ball moves upward, gravity slows it and then causes it to fall back to the ground. The path of the ball can be modeled by the equation h-16+80 What is a reasonable domain for the time the ball is in the air? Nicholas throws a ball into the air with an initial upward velocity of 80 ft/sec. As the ball moves upward, gravity slows it and then causes it to fall back to the ground. The path of the ball can be modeled by the equation h(t)-16r +80 What is a reasonable range for the height of the ball?Explanation / Answer
5. h(t) = - 16 t^2 + 80 t = 0
t ( - 16t + 80 ) = 0
t= 0 or 5 sec
domain: (0 to 5 sec)
6. h will max for time at which dh/dt= 0
- 32 t + 80 = 0
t = 2.5 sec
h(2.5) = 100 ft
