1. ### A car is driven 115 km west and then 95 km southwest. What is the displacement of the car from the point of or?

greenshark19 is wrong, i think. The displacement is 194.17m from the origin, and the direction is [200.24degrees] or 20.24degrees south of west.

4. ### An electric field of 420000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of -8.0C at t..?

Simply F = q * E I get F = 3.4e6 N to two significant digits. Now if you meant -8.0 µC, then F = 3.4 N Hope this helps!
