Q1. A 1000 kg car travelling at a speed of 20 m/s skids to a halt on wet concrete where f_k = 0.50. How long is the cars skid marks?

Q2. The potential at location A is 481 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 878 V, and when released from rest from this spot, the particle arrives at B with twice the speed it before had, or 2 vB. Find out the potential at B.
