Bank robbers leave the bank with the bounty. The cops get alerted right away, but it takes them 5 minutes before they start in hot pursuit. The police station is 10 miles down the road from the bank in the direction opposite to that in which the robbers are heading. If the robbers travel at 97 mph how fast must the cops go to catch them before they reach the state line 55 miles away? Round your answer to nearest mile per hour.

Three particles with charges q₁ = +10 μC, q₂ = -20 μC and q3 = +30 μC, are positioned at the vertices of an isosceles triangle with sides a = 0.1 m b = 0.06 m as shown in the Figure. How much work must we do to exchange the positions of q₁ and q3 ? Give your answer in Joules. Hint: What is the Energy of the system of 3 charges as they are and what is its Energy when the positions of 91 and 93 are exchanged? What does the difference between these energies represent?
