College Physics Newtonian Mechanics) In a collision between a huge SUV and a small hybrid car, the SUV exerts a larger force on the hybrid than the hybrid
... [Show More] exerts on the SUV. A) True B) False C) It depends on whether the collision is a head-on collision or a rear-end collision.A box is placed on a table which rests on the floor. The box pushes on the table; the reaction force to the box's push on the table is the table's push on the floor. A) True B) FalseIn order to get an object moving, you must push harder on it than it pushes back on you. A) True B) FalseA girl attaches a rock to a string, which she then swings counter-clockwise in a horizontal circle. The string breaks at point P in the figure, which shows a bird's-eye view (as seen from above). Which path (A-E) will the rock follow? A) Path A B) Path B C) Path C D) Path D E) Path EIf you pound a feather with a hammer, which one feels a greater force? A) always the feather B) always the hammer C) The size of the force is always exactly the same on both of them. D) If the feather moves, then it felt the greater force. Otherwise the force was the same on both.A satellite is in orbit around the earth. Which one feels the greater force? A) the satellite because the earth is so much more massive B) the earth because the satellite has so little mass C) Earth and the satellite feel exactly the same force. D) It depends on the distance of the satellite from Earth.You pull on a crate with a rope. If the crate moves, the rope's pull on the crate must have been larger than the crate's pull on the rope, but if the crate does not move, both of these pulls must have been equal. A) True B) False) In order to lift a bucket of concrete, you must pull up harder on the bucket than the bucket pulls down on you. A) True B) FalseIf the rockets of a spaceship in outer space (far from all gravity) suddenly lose power and go off, the spaceship will gradually slow to a stop. A) True B) FalseYou are in a train traveling on a horizontal track and notice that a piece of luggage starts to slide directly toward the front of the train. From this observation, you can conclude that this train is A) speeding up. B) slowing down. C) changing direction. D) speeding up and changing direction. E) slowing down and changing direction.While flying horizontally in an airplane, you notice that a string dangling from the overhead luggage compartment hangs at rest at 15° away from the vertical toward the front of the plane. Using this observation, you can conclude that the airplane is A) moving forward. B) moving backward. C) accelerating forward. D) accelerating backward. E) not accelerating because the string is at rest.An elevator suspended by a vertical cable is moving downward but slowing down. The tension in the cable must be A) greater than the weight of the elevator. B) less than than the weight of the elevator. C) equal to the weight of the elevator.A crate is sliding down an inclined ramp at a constant speed of 0.55 m/s. The vector sum of all the forces acting on this crate must point A) down the ramp. B) up the ramp. C) perpendicular to the ramp. D) vertically downward. E) None of the above choices is correct.A bucket is being lowered by a very light rope with a constant downward velocity. The tension in the rope must be A) equal to the weight of the bucket. B) greater than the weight of the bucket. C) less than the weight of the bucket.) Bill and his daughter Susan are both standing on identical skateboards (with really good frictionless ball bearings), initially at rest. Bill weighs three times as much as Susan. Bill pushes horizontally on Susan's back, causing Susan to start moving away from Bill. Just after Bill stops pushing, A) Susan and Bill are moving away from each other, and Susan's speed is three times that of Bill. B) Susan is moving away from Bill, and Bill is stationary. C) Susan and Bill are moving away from each other, with equal speeds. D) Susan and Bill are moving away from each other, and Susan's speed is one-third that of Bill.You push on box G that is next to box H, causing both boxes to slide along the floor, as shown in the figure. The reaction force to your push is A) the push of box G on box H. B) the push of box H on box G. C) the push of box G against you. D) the upward force of the floor n box G. E) the acceleration of box G [Show Less]
