The change in an object's momentum is equal to the product of the mass of the object and the time interval. the net external force divided by the time interval. the product of the force applied to the object and the time interval. the time interval divided by the net external force. Which of the following situations is an example of a visible change in momentum? A car drives over a pebble. A hiker walks through a spider's web. A baseball is hit bv a bat. A volleyball hits a mosquito in the air. IIi'll'hen comparing the momentum of two moving objects, which of the following is correct? The more massive object will have less momentum if its velocity is greater. The object with the higher velocity will have less momentum it the masses are equal. The less massive object will have less momentum it the velocities are the same. The more massive object will have less momentum it the velocities are the same. IIi'il'hich of the following has the greatest momentum? truck with a mass of 5131 kg moving at a velocity of 1i] ml's car with a mass of 154i] kg moving at a velocity of 38 mils truck with a mass of 225i} kg moving at a velocity of 25 mils car with a mass of 121i] kg moving at a velocity of 51 mls The impulse experienced by a body is equivalent to the body's change in momentum. velocity. force. kinetic energy. A force is applied to stop a moving shopping cart. Increasing the time interval over which the force is applied requires the same force. has no eect on the force needed. requires a greater force. requires a smaller force. A ball with a mass of [1.1 5 kg and a velocity of 5.0 Ms strikes a wall and bounces straight back with a velocity of 3.0 rni's. 1|.I"|||'hat is the change in momentum of the ball? 1_2EI kg-rnl's U.15 kg-rnl's l]_3[i kg-rnl's T.5ll kg-rni's A baseball is pitched very last. Another baseball of equal mass is pitched very slowly. Which of the following statements is conect'? The fastmoving baseball is easier to stop because it has more momentum. The slow-moving baseball is harder to stop because it has more momentum. The slow-moving baseball is easier to stop because it has more momentum. The fastmoving baseball is harder to stop because it has more momentum. Which of the following statements properly relates the variables in the equation FM = Ap? A large constant force changes an object's momentum over a long time interval. A large constant force acting over a long time interval causes a large change in momentum. A large constant force changes an object's momentum at various time intervals. A large constantforce does not necessarily cause a change in an object's momentum. A softball with a mass of 0.11 kg moves at a speed of 12 m/s. Then the ball is hit by a bat and rebounds in the opposite direction at a speed of 15 m/s. What is the change in momentum of the ball? -0.33 kg-m/s -1.3 kg-m/s -3.0 kg-m/s -1.6 kg-m/s An ice skater initially skating at a velocity of 3 m/s speeds up to a velocity of 5 m/s. The momentum of the skater remains the same. . becomes zero. . . decreases. increases. A moderate force will break an egg. However, an egg dropped on the road usually breaks, while one dropped on the grass usually does not break because for the egg dropped on the grass, the change in momentum is less. . the time interval for stopping is greater. the change in momentum is greater. the time interval for stopping is less. If a force is exerted on an object, which statement is true? . A small force produces a large change in the object's momentum. . A small force applied over a long time interval can produce a large change in the object's momentum. . A large force produces a large change in the object's momentum only if the force is applied over a very short time interval. A large force always produces a large change in the object's momentum. A 6.0 * 10 2 kg tennis ball moves at a velocity of 12 m/s. The ball is struck by a racket, causing it to rebound in the opposite direction at a speed of 18 m/s. What is the change in the ball's momentum? -1.1 kg-m/s . . . -0.72 kg-m/s -0.38 kg-m/s -1.8 kg-m/s Which of the following has the greatest momentum? turtle with a mass of 91 kg moving at a velocity of 1.4 m/s . . . tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s hare with a mass of 2.7 kg moving at a velocity of 7 m/s . roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s
