Questions 1. What kind of information is indicated by the graph of the acceleration due to gravity versus ball's mass if the slope of the curve is zero? 2. A ball is dropped from the roof of a building. The ball strikes the ground after 6 s. a) How tall, in meters, is the building? b) What is the magnitude of the ball's velocity just before it reaches the ground? 3. A student throws a ball vertically downward from the top of a building. The ball leaves the thrower's hand with a speed of 10m/s. a) What is its speed after falling for 1s? 2 s? 3 s? How far does it fall in 1 s? 2 s? 3 s? b) c) What is the magnitude of its velocity after falling 10 m? 4. A ball is thrown straight up in the air. What is its acceleration at the instant it reaches its highest point? Does the acceleration due to gravity change either in magnitude or in direction, when the velocity of the ball changes direction? Ignore air resistance. 5. What are some examples of falling objects, in which it would be unreasonable to neglect air resistance?
