Question

I have this question before, it wasn’t completed all the way and the graphing was weird. I’ve commented on that post can I have a redo of the entire post question...

5. An object's motion is represented by the x vs. t graph Hint: Velocity is the slope of x vs. t graph, and acce [30 points: 5 points each] shown below. leration is slope of v vs. t graph. r (s) r (s) a. Draw the corresponding v vs. t graph on the axes provided. b. Draw the corresponding a vs. t graph on the axes provided. c. At what times is the position a maximum (most positive)? At those times, is the velocity a maximum, minimum, or zero? At those times, is the acceleration a maximum, minimum, or zero? d. At what times is the position a minimum (most negative)? At those times, is the velocity a maximum, minimum, or zero? At those times, is the acceleration a maximum, minimum, or zero? At what times is velocity a maximum (most positive)? At those times, what is the position of the object? Give a simple relationship between the sign of the position and the sign of the e. f. acceleration at the same instant of time. Page 3 of 4

Answer 1

C position is maximum and 3.5 s.............

velocity is zero at that time

acceleration is constant

D.

position is minimum at 0.5 s and 2.5 s

velocity is zero at that time

acceleration is constant

E. position and accelaration has different signs

ie. if accelaration is positive the position is negative

velocity is maximum at 1 s and 3 s

position is zero at that time

acceleration is constant
