A motorist drives south at 30.0 ms for 3.00 min then turns, Ask an Expert

Academics

Q1. A motorist drives south at 30.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.80 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.8 min trip, how do you find the total vector, average speed and average velocity?

Q2. Now presume that the particle "chooses" a different way of traveling. Compute the total amount of work completed by the electrostatic force on the charged particle as it moves from A to D to C.
