The kinetic energy, k, of an object with mass m moving with velocity v can be found using the formula - e_{\text{k}}={\tfrac {1}{2}}mv^{2} . a scientist measured the velocity of a 5-kilogram object and a 20-kilogram object in an experiment. if the velocity of the 5-kilogram object was twice the velocity of the 20-kilogram object, what was the ratio of the kinetic energy of the 5 kilogram object to the kinetic energy of the 20-kilogram object?

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?
