Megan and Kim are out playing miniature golf. Megan hits the golf ball and it begins to roll up a hill toward a the hole at a velocity of 2.0 m/s. Assuming that the direction toward the hole is positive, what is the velocity of the golf ball after 2.5 seconds, if it slows at a constant rate of -0.50 m/s2?

Ms. Warzecha wants to test how accurate Earth’s acceleration of gravity is in New Braunfels. She heads out to Cougar Stadium and drops a tennis ball off the top of the stadium stands. She records a drop time of 1.90 seconds. The stadium stands are 15.0 meters tall. What is the acceleration of the tennis ball?

To earn extra-credit for their physics class, Savannah and Ashley go to the top of the Tower of the Americas to conduct a little experiment. Savannah spits over the edge of the observation deck and Ashley, using a stopwatch, records the time it takes for the spit to hit the ground. If the observation deck is 123000 mm above the ground, how long will it take for her spit to hit?
