Based on the calculations, it would take 7.5 seconds before the final velocity of this object would be equal to three times its initial velocity.
<u>Given the following data:</u>
- Initial velocity = 15 m/s.
- Constant acceleration = 4 m/s².
- Final velocity = 3 × 15 = 45 m/s.
<h3>How to calculate the acceleration of an object?</h3>
Mathematically, acceleration can be calculated by using the first equation of motion:
v = u + at
<u>Where:</u>
- u is the initial velocity.
- t is the time measured in seconds.
Making t the subject of formula, we have:
t = (v - u)/a
Substituting the given parameters into the formula, we have:
t = (45 - 15)/4
t = 30/4
t = 7.5 seconds.
