Two horizontal forces and act on a 4.0 kg disk that slides
Chapter , Problem 12(choose chapter or problem)
Two horizontal forces \(\vec{F}_{1}\) and \(\vec{F}_{2}\) act on a 4.0 kg disk that slides over frictionless ice, on which an xy coordinate system is laid out. Force \(\vec{F}_{1}\) is in the positive direction of the x axis and has a magnitude of 7.0 N. Force \(\vec{F}_{2}\) has a magnitude of 9.0 N. Figure 5-32 gives the x component \(v_{x}\) of the velocity of the disk as a function of time t during the sliding. What is the angle between the constant directions of forces \(\vec{F}_{1}\) and \(\vec{F}_{2}\)?
