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 0.350 m/s2, how far will it travel before becoming airborne?
(b) How long does this take?
We are given
From the kinematic equations, the most applicable formula to solve for the change in distance, , is . Substituting the given values, we have
From the basic formula for acceleration, , we have the formula for time:
