7, A ball Is thrown upward from a height of is it with an Initial upward velocity of 5 It's. Use the formula hit) =-161 + vt +s to find how long it will take for the ball to hit the ground. 8. One of the games at a carnival involves trying to ring a bell with a ball by hitting a lever that propels the ball into the air. The height of the ball is modeled by the equations h(t) - -161 + 39t If the bell is 25 fl above the ground, will it be hit by the bal 9. A ship drops anchor in a harbor. The anchor is 49 it above the surface of the water when it is released. Use the vertical motion formula hit) = - 168 + ut + s to answer the following questions. a. What is the value of s, the starting height? b. What is the value of h when the anchor hits the water? The starting velocity is zero. After how many seconds wl ichar hit the water?10. An amateur rocketry club is holding a competition. There is cloud cover at 1000 ft, If a racket is launched with a velocity of 315 /s, use the function hit) = -16+ + ut + he to determine how long the rocket is out of sight. BOMO etl8.

You and a friend are hiking in the mountains. You want to climb to a ledge that is 20 it above you. The height of the grappling hook you throw is given by the function h(t) = - 161+ 321 +5, What is the maximum height of the grappling hook? Can you throw it high enough to reach the ledge? 5. You are trying to dunk a basketball. You need to jump 2 5 fi in the air to dunk the ball. The height that your feet are above the ground is given by the function hit) . . 161 4 121 What is the maximum height your feet will be above the ground? Wil you be able to dunk the basketbal? 5. A diver is standing on a platform 24 ft above the pool. He jumps from the platform with an initial upward velocity of & It/s, Use the formula h(t) = =16t + ut + s, where h is his height above the water, I is the time, v is his starting upward velocity and s is his starting height.
