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:
