Wags decides to go on another adventure. He begins by traveling east for 100m. He then moves 75 m in a direction 60◦ west of south. Finally, he accelerates at a rate of 2.5 m/s2, from rest, directly north. How far is he from his starting location 10seconds after he began accelerating? - I know we have to find the displacement but then what?

A driver is traveling along a straight road at the speed limit V. After 2min, she slows at a constant rate to a stop at a traffic light. Two minutes laterthe light turns green, and she accelerates at a constant rate back up to thespeed limit. Five minutes later she again slows at a constant rate to a stop.After 3 min she performs a u-turn then accelerates at a constant rate back upto speed V. Two minutes later she reaches her destination and slows at aconstant rate to a stop. Sketch a graph of velocity versus time that representsher trip
MY NOTES ASK YOUR TEACHER A cab driver heads south with a steady speed of v, -20.0 m/s for t-3.00 min, then makes a right turn and travels at v₂ - 25.0 m/s for fy 2.20 min, and then drives northwest at v₂ - 30.0 m/s for ty-1.00 min.

Analysis Mo Constant Velocity 6. A car travels along a straight line at a constant speed of AMT 60.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 30.0 mi/h. (a) What is the con- stant speed with which the car moved during the second dis- tance d? (b) What If? Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the same constant speed as found in part (a). What is the average velocity for this trip? (c) What is the average speed for this new trip?
