Since the slope of the linear fit is 0.0541 m/s 2 (yes, the slope has units), then the acceleration of this cart would be 0.108 m/s 2. Boom. The Common Student Method ...

The common problem is to draw a velocity graph that LOOKS like the acceleration graph. ... Notice in this position graph, the SLOPE is ... This would give a net force of 1.4 g's at a 45° angle ...
