1. A 1.500 kg mass is suspended from a string. The string, which runs over a pul- ley, is attached to a dynamics cart weighing 546 g and resting on an inclined plane with an angle of 32.0° from the horizontal. What is the calculated acceleration of the cart up the incline in meters per second squared? Assume that the positive x-axis points up the incline.​
