Average Velocity

Question

A particle’s position as a function of time is described as $y (t) = 2 t^{2} + 3 t + 4.$ What is the average velocity of the particle from $t = 0 t o t = 3 \sec ?$

Moderate

A

3 m/sec
B

6 m/sec
C

9 m/sec
D

12 m/sec

Solution

$v (t) = 4 t + 3 < v > = \frac{\int v d t}{\int d t}$
