# Newton's second law and equations of motion

4.) A 0.840 kg glider on a level air track is joined by strings to two hanging masses. The strings have negligible mass and pass over light, frictionless pulleys.

a.) Find the acceleration of the masses and...

b.) Find the tension in the strings when the air flow is turned off and the coefficient of friction between the glider and the track is 0.47.

Please see the attached file.

The problem does not supply the hanging masses values. therefore (due to the urgency) I solved all the equations all the way through, and all you need to do is to plug in the ...
