A clarinetist, setting out for a performance, grabs his 3.49-kg
clarinet case (including the clarinet) from the top of the piano
and carries it through the air with an upward force of 35.9 N. Find
the case\'s vertical acceleration. Indicate an upward acceleration
as positive and a downward one as negative.
Applied force - gravitational force = net force
35.9 - 3.49 * 9.8 = F
So the clarinet will accelerate downwards.
Now a = F/m = 1.698 / 3.49 = 0.486 m/s^2
