A 45 kg object has a momentum of 225 kg-m/s northward. What is the object's velocity? A. 5.0 m/s
B. 180 m/s
C. 10,125 m/s
D. 0.20 m/s

State the right hand rule of the direction of magnetic field in a conductor carrying current

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?

Assume this car is driven off a cliff . how many arrows of force need to be drawn in the free body diagram? assume no air resistance -five -one -three -four
