Two closed containers look the same, but one is packed with lead and the other with a few feathers. how could you determine which has more mass if you and the containers were orbiting in a weightless condition in outer space?

You could push the containers, applying roughly the same amount of force. the container that accelerates more, going at a greater speed under the action of the applied force will the the container that has the feathers as f = ma, and the container with the feathers will have a significantly less mass than the container with the lead.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
