Question

If the car continued at the same acceleration (meaning the slope of the line does not change), how fast would it be going in 15 seconds?

Answer 1

Given constant acceleration a, the velocity of the car after 15 seconds would be given by:

$v(15) = v(0) + 15a$

• In which v(0) is the initial velocity.

The velocity of a car after t seconds is modeled by the following function:

$v(t) = v(0) + at$

In which:

• v(0) is the initial velocity.
• a is the acceleration.

In this problem, 15 seconds, hence $t = 15$ and:

$v(15) = v(0) + 15a$
