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?

Verified Answer :

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.

The final velocity of the toy car after 6.0 seconds is equal to 17 m/s.

Given the following data:

  • Initial velocity = 5.0 m/s
  • Acceleration = 2.0 \(m/s^2\)
  • Time = 6.0 seconds

To calculate the final velocity after 6.0 seconds, we would use the first equation of motion:

Mathematically, the first equation of motion is calculated by using the formula;

\(V = U + at\)

Where:

  • V is the final velocity.
  • U is the initial velocity.
  • a is the acceleration.
  • t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

\(V = 5+2(6)\\\\V =5+12\)

Final velocity, V = 17 m/s
