A skater travels in a straight line for 855 m in a direction of 25.0 degrees north of east, then 560 m in a straight line 22 degrees east of north.

a) What is the skater's resultant displacement?
b) If the motion took 4.40 min, determine the skater's average speed and average velocity.

You have a small boat which travels through water at a speed of 6.0 m/s. You take it out on a section of a local river where the water flows from north to south at a speed of 4.0 m/s. (a) First, you head south (i.e. downstream) in your boat. Draw a vector which represents the velocity of the boat relative to the water, and a vector that represents the velocity of the water relative to the shore. Then add...

Bill and Jill both average swimming speeds of 3.0 m/s, in a pool (that has no current). Bill and Jill go down to the river for a swim, the river has a current of 1.0 m/s straight EAST and is 1.50 x 102 m in width. They are standing on the SOUTH shore. a.Bill, not thinking about the current, jumps in and swims straight across to the North shore. Of course the current affects his resultant velocity and he doesn’t...

At one instant a bicyclist is 45.0 m due east of a park's flagpole, going due south with a speed of 14.0 m/s. Then 32.0 s later, the cyclist is 45.0 m due north of the flagpole, going due east with a speed of 14.0 m/s. For the cyclist in this 32.0 s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and...
