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.​

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

c) power lifting, will be your answer.
