Question
Position, Velocity, and Acceleration
Reading velocity and position from the graph
Agent Charley, who has been supervising a person (code name Snail) suspected of delivering illegal drugs. A GPS had been installed in his car, and another smaller GPS had been installed in his bicycle by the agent. At 8:00 AM, Snail parked his car at a location (determined by the GPS in his car) along an east-west highway. Snail then rode his bicycle along the highway for the next five hours. However, much information recorded by the GPS in his bicycle has been accidently erased. Only the records of the velocity of the bicycle of the first five hours are available. The following graph represents the velocity, v (in miles per hour) with respect to time t (in hours after 8:00 AM) along the highway. The positive velocities means the bike is going eastbound and negative velocities means the bike is going westbound.
The question I need help with is:
Explanation / Answer
in this question, you have to find area under the curve. take area above x axis as positive and area below x-axis as negative. by adding with sign calculate net area. this net area gives displacement from the initial location.
if net area is positive,bike is east side
if net area is negative,bike is going west side.
for total distance, add all area by considering them positive.
