Question

a bicyclist speeds up and then maintains a constant speed. the velocity-time graph represents its motion.velocity (m/s)time (s)a. determine the displacement of the object for the first 3 seconds. indicate the direction using a + or a - sign.displacement (0-3 s) 15 mb. determine the displacement of the object for the last 3 seconds.displacement (3-6 s) 30 mc. determine the displacement of the object for the entire 6 seconds.displacement (0-6 s) ___ m

Explanation:

Step1: Sum the two displacements

<Expression>
$15\ \text{m} + 30\ \text{m}$
</Expression>

Step2: Calculate total displacement

<Expression>
$45\ \text{m}$
</Expression>

Answer:

45 m
