1. If object A is moving at velocity u with respect to object B and object

B is moving with velocity wwith respect to object C then object A is moving with velocity v+wwith respect to object C. This is the Galilean law for addition of velocities, an approximation good if all the speeds are small compared to the speed of light in a vacuum c=2.9979X10⁸ m/s.

A ferry boat is moving at 10.0 m/s due Northeast with respect to the land and a dog walking on that ferry boat is moving at 5.0 m/s West with respect to the ferryboat and a tick crawling on the dog is moving at

0.2 m/s South with respect to the dog.

a) If East is iand North is j,what are the x and y components of the dog's velocity?

b) What is the angle counterclockwise from East to the dog's velocity?

c) What is the dog's speed?
