Question

A remote controlled car starts from rest and accelerates at 2 m/s² for 6.5 seconds. What is the final velocity of the car after the acceleration takes place?

Answer 1

Answer:

The final velocity of the car after the acceleration takes place is 13 m/s.

Explanation:

The final velocity can be calculated using the following equation:

$V_{f} = V_{0} + at$

Where:

$V_{0}$: is the initial velocity = 0 (starts from rest)

a: is the acceleration = 2 m/s²

t: is the time = 6.5 s

Hence, the final velocity is:

$V_{f} = V_{0} + at = 0 + 2 m/s^{2}*6.5 s = 13 m/s$

Therefore, the final velocity of the car after the acceleration takes place is 13 m/s.
