Homework Statement

Serway Physics Section 2.4 Acceleration

15. A velocity-time graph for an object moving along the x-axis is shown in Figure P2.15.
(a) Plot a graph of the acceleration versus time. Determine the average acceleration of
the object (b) in the time interval t=5.00 s to t=15.0 s and (c) in the time interval t=0 to t = 20.0 s.

Homework Equations

Velocity-time graph labeled Figure P2.15: v_x (m/s) against t (s), with v_x rising from -8 m/s at t=0 to about 8 m/s near t=16 s, then flat.

The Attempt at a Solution

Handwritten solution to Serway Section 2.4 problem 15: a step graph of acceleration a (m/s^2) versus t (s) showing 1.6 m/s^2 from t=5 to t=15 and 0 elsewhere, with average acceleration calculations of 1.6 m/s^2 and 0.8 m/s^2 for parts b and c.

Is my calculation correct?
