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

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

Step-by-step 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.

I hope it helps you!
