||||

a) Straight out of the tube. | b) Curved in the direction of the spiral. | c) Curved in the opposite direction of the spiral. | d) A parabola. | |

||||

a) Both balls hit the ground at the same distance from the table. | b) The red ball hits the ground further from the table. | c) The yellow ball hits the ground further from the table. | d) There are no balls. Itâ€™s a conspiracy. | |

Two basketballs are projected off the edge of a table, one red and one yellow. The yellow one has a mass of 5.0 g; the red one has a mass of 3.5 g. (Assume air resistance is negligible). Choose the true statement. |
||||

a) Both balls hit the ground at the same distance from the table. | b) The red ball hits the ground further from the table. | c) The yellow ball hits the ground further from the table. | d) The combined forces of gravity and centripetal acceleration will keep the ball on the table indefinitely. | |

||||

a) Both balls hit the ground at the same time. | b) The white ball hits the ground first. | c) The orange ball hits the ground first. | d) The white ball will float, because it is less dense than water. | |
