A rock is released from rest and falls in the absence of air resistance. Which of the following statements is true? Its acceleration is zero. Its acceleration is constant. Its velocity is constant. Its acceleration is increasing.
A jet plane has a takeoff speed of v 66 m/s and can move along the runway at an average acceleration of 1.9 m/s. If the length of the runway is 2.9 km, will the plane be able to use this runway safely? O Yes O No Defend your answer.
A ball is thrown straight upward with an initial speed of 34 m/s. Assuming no air resistance, how much time (in seconds) will it take for the ball to reach its maximum height?
As a body falls through air starting from rest, its velocity (don't ignore the air resistance) stays constant. continuously decreases. continuously increases. gets larger and larger, eventually reaching a constant value. gets smaller and smaller, eventually approaching zero.
A cargo helicopter, descending steadily at a speed of 4.5 m/s, releases a small package. Let upward be the positive direction for this problem.

(Indicate the direction with the sign of your answer.)
If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance. What is its vertical displacement (in m) after 10 s? (g = 10 m/s2)
Which of the following are true? As a ball falls freely in a vacuum, it falls the same distance each second. A ball is thrown straight up. At the top of its path, its velocity is zero. An object in freefall has different acceleration when it is going downward compared to when it is going upward. In freefall, an object’s velocity is proportional to the distance it has falls from rest – that is, an object that has fallen 10 m (from rest) is going twice as fast as when it had fallen only 5 m. A ball is thrown straight up. At the top of its path, its acceleration is zero.
