(a) What is the momentum in kg . m/s of a garbage truck that is 1.10 x 10* kg and is moving at 27.0 m/s? (Enter a number.) kg . m/s (b) At what speed in m/s would an 8.00 kg trash can have the same momentum as the truck? (Enter a number.) m/s -/2.85 Points] DETAILS OSCOLPHYS2016ACC 8.2.P.018. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A 0.350 kg hammer is moving horizontally at 7.00 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board. (a) Calculate the duration of the impact in seconds. (Enter a number.) S (b) What was the average force in newtons exerted downward on the nail? (Enter a number.) N [-/2.85 Points] DETAILS OSCOLPHYS2016ACC 8.3.P.023. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 130,000 kg and a velocity of 0.300 m/s, and the second having a mass of 95,000 kg and a velocity of -0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)? (Enter a number.) m/s
