4. Free Fall from the Tower of Pisa: Had Galileo dropped a ball from the Tower of Pisa, 185 feet above the ground, the ball’s height above the ground t sec into the fall would have been s=185-16t^2.

a.) What would have been the ball’s velocity and acceleration at time t?

Velocity: _______________________ Acceleration: ___________________

b.) About how long would it have taken the ball to hit the ground SHOW WORK!

Time: ________________ (Include three decimal places and units
