Q1. A hiker's trip consists of three segments. Path A is 8.0 km long heading 60degrees north of east. Path B is 7.0km long in a direction due east. Path C is 4.0 km long heading 315 degrees counter clockwise from east.

a) Graphically add the hiker's displacement in A, B, C

b) graphically add the hiker's displacement in C, B, A

Q2. A proton is initially at rest at a point where the potential is 461V. Sometime later the proton is at a point where the potential is 191V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy?
