Solve. (Use 4.9t2 +vot=s, where Vo is initial velocity, t is time, and s is distance.) a) A bolt falls off an airplane at an altitude of 300 m. Approximately how long does it take the bolt to reach the ground? b) A ball is thrown downward at a speed of 20 m/sec from an altitude of 300 m. Approximately how long does it take the ball to reach the ground? c) Approximately how far will an object fall in 5 sec, when thrown downward at an initial velocity of 20 m/sec from a plane? ID a) It takes the bolt to reach the ground. (Simplify your answer. Type an integer or a decimal rounded to the nearest tenth as needed.) b) It takes the ball to reach the ground. (Simplify your answer. Type an integer or a decimal rounded to the nearest tenth as needed.) c) The object will fall (Simplify your answer. Type an integer or a decimal rounded to the nearest tenth as needed.)
