Elj A ball rolling down an incline has its maximum potential energy at Aj the top B the bottom g halfway down. Of a quarter of the way down. 87 Impulse involves the time that a force acts, whereas work involves the Aj acceleration that a force produces. Bj distance that a force acts. C) time and distance that a force acts. 830 A block of ica sliding down an incline has half its maximum kinetic energy Aj halfway down. By at the top. C at the bottom D) need more information #4) Two identical amoves, one with twice the Hartic mery of the other, are fired into a bale of hay. Compared with penetration of the slow arrow, the finster arrow panelmates A) more than four times as far. Bj the same distance. C four times as far. Dj twice as far. Ej inone of the above #5) The emphasks of the orange-and-apple sequence in your textbook is Aj defining systems Bj actions equal reactions. g mas is not a force Dj forces produce accelerations. E) friction is a force. Bej Nellie tosses a ball upward at an angle. Neglecting air resistance, the variical component of the initial velocity A) Increases with time to reach the top. B) remains comtiant. C doorvines with time to reach the top. #7) As a ball falls, the action force is the Earth's pull on the ball. The reaction force is the Aj ball's pull on Earth By air resistance acting againd the ball g acceleration of the ball Of none of the above BB) 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-reaction pair of foron. Bj do not make an action-reaction pair of forces. C ineed more information Big An archer shoots an amow. Consider the action foron to be the bowstring agained the arrow. The reaction to this force is the A) grip of the archer's hand on the bow. Bj friction of the ground against the archar's foot. Q arow's push against the bowstring. Dj combined weight of the anow and boundringtoj 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. ineed more information #1) When Nellis hangs suspended from a pair of ropes that are not vertical, the landon in each rope is Aj halfha weight. B) less than half har weight. gha wright. Dy more than half her weight. #2) The force due to gravity that acts on a block of ice that slides down an icy rump Aj decromes as the slope of the ramp increimers. Bj becomes greated when the ramp is vertical. C remains equal to my at all angles. #3) Neglecting air resistance, once a tossed ball leaves your hand Aj your tosing force remains while the ball goes upward. Bj inertia becomes the force acting on it. C your tossing force remains until it comes to a stop. Dj only the force due to gravity acts on it. E) ina further forces act on it. #4) if vertically falling rain makes slanted 45" streaks on the side windows of a moving car, the speed of the er A) exceeds the speed of the falling drops. B) is less than the speed of the falling drops C equals the speed of the falling drops. Dy need more information 45) When a ball falls downward, it may have a net force Bj equal to iits weight minus air drug. G equal to lifts weight. [Dj any of the above E) inone of the above "8) A river 100 m wide flows due south at 1 mis. A boat that goes i mis relative to the water leaves the west bank. To land at a point due out of its starting point, the boat must be pointed A) northant. Bj nowhere-it can't be done. g southeast "7) The force on a dropped apple hitting the ground depanck upon Aj the time of contact with the ground. B whether or not the apple bounces. C the speed off the apple just before it hits. Of all of the above "8) The manage braking force of a 1000-bg car moving at tom's braking to astop in 5 s is Aj 5000 N. BJ TOOD N. CI MINO N. DJ 400ON. EJ MOON. "7) When Peter tosses an egg against a sagging sheet, the egg doesn't break due to Aj reduced impulan B) reduced momentum. G both of those Do neither of there
