Question

A clarinetist, setting out for a performance, grabs his 3.05-kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 34.4 n. find the case\'s vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

Answer 1

The net force is

`F_(net)=-mg+34.4N = (-3.05kg) (9.8 (m)/(s^2))+34.4N=4.51N`
And then

`F=ma=4.51N`

`a=4.51N/3.05kg=1.4787 (m)/(s^2)`
