Question
The graph below shows the distance versus time for an elevator as it moves up and down in a building. Compute the elevator's velocity at the times marked a, b, and c. (Assume the distance is measured from ground level and the positive direction is upward.)
Time a
Time b
Time c
rise
Your value is acceptable. m run
s The graph below shows the distance versus time for an elevator as it moves up and down in a building. Compute the elevator's velocity at the times marked a, b, and c. (Assume the distance is measured from ground level and the positive direction is upward.) Compute the elevator's velocity at time a. (Use your estimates. Indicate the direction with the sign of your answer.) Compute the elevator's velocity at time b. (Use your estimates. Indicate the direction with the sign of your answer.) Compute the elevator's velocity at time c. (Use your estimates. Indicate the direction with the sign of your answer.)
