An object is dropped from a tower, 199 ft above the ground. The object's height above groundt sec into the fall is s = 199 – 16t2. a. What is the object's velocity, speed, and acceleration at time t? b. About how long does it take the object to hit the ground? c. What is the object's velocity at the moment of impact?
