#### A swan on a lake gets airborne by flapping its wings and running on top of the water.

(a) If the swan must reach a velocity of 6.00 m/s to take off and it accelerates from rest at an average rate of , how far will it travel before becoming airborne?

(b) How long does this take?

**SOLUTION:**

Part a.

We are given

From the kinematical equations, the most applicable formula to solve for the change in distance, , is . Substituting the given values, we have

Part b

From the basic formula for acceleration, , we have the formula for time:
