일반물리학 1 — Force and Motion-I: Problem 63

63 Figure 5-45 gives, as a function of time \(t\), the force component \(F_x\) that acts on a 3.00 kg ice block that can move only along the \(x\) axis. At \(t = 0\), the block is moving in the positive direction of the axis, with a speed of 3.0 m/s. What are its (a) speed and (b) direction of travel at \(t = 11\) s?
