Vertical Motion Models


Use the vertical motion model: NAME DATE PERIOD ALGEBRA 2 SECTION 43 DAY to solve each problem.


  1. To celebrate July 4, the town of Trigon has hired Pyro Tech, Inc to launch fireworks from an 80 foot tower in the center of town. The rockets can be fired with an initial upward velocity of 64 feet per second.


  1. Write a vertical motion model for this problem: __________________________________

  2. Find the vertex: __________________

c.) When does the rocket reach its maximum height? ___________

d.) How high will the rocket go? ___________

e.) How long after the launch will the rocket debris hit the ground? ___________




  1. A diver springs from the edge of a cliff 80 ft above the ocean with an initial upward velocity of 8 feet per second. How long will it take the diver to reach the water?








  1. A circus acrobat is shot out of a cannon with an initial upward speed of 50 feet per second. If the acrobat leaves the cannon 4 ft above the ground, how high in the air will he go?








  1. At a pep rally, cheerleaders use a slingshot to launch small, foam basketballs into the crowd from the ground. The balls are shot with an initial upward velocity of 36 feet per second. Suppose no one catches the ball, how long will it take to hit the ground?









Use the vertical motion model: NAME DATE PERIOD ALGEBRA 2 SECTION 43 DAY to solve each problem.


  1. A baseball player hits a pitched ball when it is 4 ft above the ground. The initial upward velocity is 80 feet per second. How long will it take for the ball to hit the ground?









  1. A flare is launched from the deck of a lifeboat 8 ft above the water surface. The initial upward velocity is 120 feet per second. How long will it take for the flare to return to the sea?
