D) a quarter of the way down. #7j Impulse involves the time that a force acts, whereas work involves the Aj acceleration that a force produces. Bj distance that a foron acts. C) time and distance that a force acts. 830 A block of ice sliding down an incline has half its maximum kinetic energy Aj halfway down. By at the top C at the bottom. 1Dy need more information #4) Two identical amoves, one with twice the Garlic maergy of the other, are fired into a bale of hay. Compared with panetration of the slow arrow, the finder arrow pandimites A) more than four times as far. B) the same disilanca. G four times as far. Dj twice as far. Ej inone of the above #5) The emphasis of the orange-and-apple sequence in your textbook is Aj defining systema [Bj actions equal reactions. C mas is not a force. Dj forces produce accelerations. E) friction is a force. #8) Nellie bosses a ball upward at an angle. Neglecting air reviclance, the variical component of the initial velocity Aj Increases with time to reach the top. Bj remains constant. C doorcomes with time to reach the top. #7) As aball falls, the action force is the Earth's pull on the ball. The reaction force is the Aj bill's pull on Earth. By Fir insistance acting againi the ball C) acceleration of the ball By none of the above BBQ While you stand on the floor you are pulled downward by gravity, and supported upward by the floor. Gravity pulling down and the support force punching up A) make an action-ireaction pair of foron. Bj do not make an action-reaction pair of forces. C ineed more information Big An archer shooks an arrow. Consider the action foron to be the bowstring against the arrow. The reaction to this force is the Aj gip of the archer's hand on the bow. Bj friction of the ground against the archer's foot. G amow's punch against the bowstring. Dj combined weight of the arrow and bowniring40) When you rub your hands together, you Aj can push harder on one hand than the other. Bj cannot push harder on one hand than the other. C ineed more information ") When Nellis hangs suspended from a pair off ropes that are not vertical, the fanion in each rope is Aj half ha wright. less than half har weight. g ha wright. D) more than half her weight. #2) The force due to gravity that acts on a block of ice that slides down an icy ramp Aj decraines as the slope of the ramp increases. Bj becomes greated when the ramp is vertical C remains equal to my at all angles. #3) Neglecting air resistance, onon a tossed ball leaves your hand Al your looking force remains while the ball goes upward. Bj Inertia becomes the force acting on it. G your tossing force remains until it comes to a stop. IDj only the force due to gravity acts on it. (E) no further forces act on it. wj If vertically falling rain makes slanted 45* streaks on the side windows of a moving car, the speed of the car Aj exceeds the speed of the falling drops. B G las than the speed of the falling drops. C equals the speed of the falling drops. Do need more information 15) When a ball falls downward, it may have a net force Bj aquil to its weight minus air drug. C equal to its wright.
