Question

A toy car is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s656-03-02-00-00_files/i0290000.jpg. What is the final velocity after 6.0 s?

Answer 1

Answer:

Final velocity of the car, v = 17 m/s

Explanation:

It is given that,

Initial velocity of the car, u = 5 m/s

Acceleration of the car, $a=2\ m/s^2$

Time, t = 6 s

We need to find the final velocity of the car after 6 seconds. It can be calculated using first equation of motion as :

$v=u+at$, v is the final velocity of the car

$v=5+2\times 6$

v = 17 m/s

So, the final velocity of the car is 17 m/s. Hence, this is the required solution.

Answer 2

It would be 17 m/s

If we use

V2 = V1 + a*t
Sub in 5 for v1
2m/s*2 for a
And
6 for t
That should give you the answer.
