1. You are in a kayak which can move at a velocity of 2.6 m/s when in still water. You are attempting to cross a river which is 110 across and which is flowing to the East at a speed of 0.4 m/s. You head directly North across the river.

a. How long does it take you to get to the other side?

b. How far downriver are you when you reach the other side of the river?

c. If you now head back upriver, how long does it take you to reach a point on the river opposite from where you started?

2. You are playing raquetball at the rec center. When you are 10 m away from the wall you hit a ball 30 m/s towards the wall at an angle of 30 degrees. Ignore any affects due to air resistance.

a. How long is the ball in the air before it hits the wall?

b. How high above the launch point does the ball hit the wall?
