an airplane innitially flying at a speed of 60 m/s accelerates at 5.0 m/s^2 for 600 meters. What is its velocity after this acceleration?

Answer 1

Start by identifying each of the given quantities, as well as the unknown, according to standard symbols:

v_i = 60 m/s a = 5 m/s² d = 600 m v_f = ?

Next look for a kinematics (uniform acceleration) equation that includes each of these quantities. If the equations your class uses includes this one:

v_f² = v_i² + 2ad

then you can solve the problem in a single step. Simply make the appropriate substitutions. Note that the equation finds the square of final velocity, so you will need to take a square root.
