The force shown in the figure below is the net eastward force acting on a ball. The force starts rising at t=0.012 s, falls back to zero at t=0.062 s, and reaches a maximum force of 35 N at the peak. Determine with an error no bigger than 25% (high or low) the magnitude of the...

Only two horizontal forces act on a 3.0 kg body that can move over a frictionless floor. One force is 9.0 N, acting due east, and the other is 6.9 N, acting 54° north of west. What is the magnitude of the body's acceleration?

I have a question about fluids ok... I've been told that Pressure = (density of fluid) (gravity) (height) ok that's great in all but I don't see how it works... Pressure = (Force perinduclar to area force is acting on)/(Area force is acting on) ok this great and all but leads ...
