What is the momentum of a 50-kilogram ice skater gliding across the ice at a speed of 5 m/s? (1 point)
10 kg • m/s
500 kg • m/s
50 kg
250 kg • m/s

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

If a balloon is taken outside on a very cold day, what will occur?

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
