Document Summary

For questions 2 and 3, please show complete solutions and explain your reasoning, stating any principles that you have used. For each of the following five questions, please circle one answer only. (i) the figure below shows the velocity-versus-time graph for a robot. If the angle between the force and the displacement is 135 . The work done by this force is (v) two points, a and b, are on a disk that rotates about an axis. Point a is three times as far (a) negative (b) positive (c) 0 (d) varying from negative to positive (e) varying from positive to negative from the axis as point b. If the speed of point b is v, what is the speed of point a? (a) v (b) 3v (c) v/3 (d) 9v (e) v3. A river is 1. 2 km wide and its current is flowing at 3 km/h.
