Marsha hits a tennis ball upward from the top of a 90 foot high cliff with an initial velocity of 16 ft/s. Marsha hit the ball when it was 6 ft. above the top of the cliff.
a. assume that the tennis ball will hit the ground below the cliff. Determine the equation for the height of the ball after t-seconds. Hint: If the initial height is 6 feet, how would you write a distance 90 feet below that height? Would you want to use the equation
h(t)=-16t^2+vt+h?
