1. A man is walking inside a railway boxcar at 3.0 m/s (N) relative to the boxcar. The boxcar is rolling along a ferryboat at 5.0 m/s (S) relative to the ferryboat. The ferryboat is heading north at 4.0 m/s. What is the velocity of the man relative to a) the ferryboat b) the water

we need to know the time interval during which the force acts. impulse of force = momentum change

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
