Atruck going 15 kmôź°€h has a head-on collision with a small car going 30 kmôź°€h. which statement best describes the situation? (a) the truck has the greater change of momentum because it has the greater mass. (b) the car has the greater change of momentum because it has the greater speed. (c) neither the car nor the truck changes its momentum in the collision because momentum is conserved. (d) they both have the same change in magnitude of momentum because momentum is conserved. (e) none of the above is necessarily true. 2. a small boat coasts at constant speed under a bridge. a heavy sack of sand is dropped from the bridge onto the boat. the speed of the boat (a) increases. (b) decreases. (c) does not change. (d) without knowing the mass of the boat and the sand, we canâ€™t tell.

1.an 8-kilogram bowling ball is rolling in a straight line toward you. if its momentum is 16 kg•m/s, how fast is it traveling? 2.a beach ball is rolling in a straight line toward you at a speed of 0.5 m/sec. its momentum is 0.25 kg•m/s. what is the mass of the beach ball? 3.a 4,000-kilogram truck travels in a straight line at 10.0 m/s. what is its momentum? momentum = (mass) x (speed) = (4,000) x (10) = 40,000 kilogram-meters/second 4.a 1,400-kilogram car is also traveling in a straight line. its momentum is equal to that of the truck in the previous question. what is the velocity of the car? 5.which would take more force to stop in 10 seconds: an 8.0-kilogram ball rolling in a straight line at a speed of 0.2 m/s or a 4.0-kilogram ball rolling along the same path at a speed of 1.0 m/s? 6.the momentum of a car traveling in a straight line at 20 m/s is 24,500 kg•m/s. what is the car’s mass? 7.another pitcher throws the same baseball in a straight line. its momentum is 2.1 kg•m/s. what is the velocity of the ball? 8 a 1-kilogram turtle crawls in a straight line at a speed of 0.01 m/s. what is the turtle’s momentum?
