Question

A box proceeds along the x-axis and the figure below shows a record of its velocity as a function of time. Every gridline along the vertical axis corresponds to 2.00 m/s and each gridline along the horizontal axis corresponds to 0.500 s. (Enter your answers in m/s². Indicate the direction with the signs of your answers. Note that t = 0

 at the intersection of the axes.)

(a) Determine the average acceleration of the box in the time interval t = 0

 to t = 2.50 s

(b) Determine the average acceleration of the box in the time interval t = 2.50 s

 to t = 7.50 s.

(c) Determine the average acceleration of the box in the time interval t = 0

 to t = 10.0 s.

Answer 1

(a) a = (-16m/s - (-16m/s))/2.5 s = 0

(b) a = (16m/s - (-16m/s))/5s = 6.4 m/s²

_{(c) a = (16m/s - (-16m/s))/10s = 3.2 m/s}²
