Hi guys. We did an experience on an inclined plan and I got this acceleration: -0,324 m/s2 . Now all I know is this: the mass of the object was 552g. g = -9,8 m/s2 and I need to find out what was the angle of the plane. I have to give this tomorrow so I need help on this please.. the teacher gave us a hint with this -gsinx but if I use that it gives me an angle of less than 2degrees. Can somebody help me on this easy question please?
