ACCELERATION

Before we solve this problem, first thing we should do is to analize the given. If it starts from rest, the initial velocity V0 = 0.

Given:

• Final speed: V = 15 m/s
• Time: t = 3s
• Acceleration: a = ?

Now, let's proceed to the solution:

[tex]V = V0 + at \\ \\ 15 = 0 + a \times 3 \\ \\ a = 5m/ {s}^{2} [/tex]

Therefore, the acceleration of a car is 5 m/s².

The formula to calculate acceleration is:

• Acceleration = Change in Velocity / Time taken

Given:

• Initial velocity = 0 m/s (stationary position)
• Final velocity = 15 m/s
• Time taken = 3 seconds

Substitute in the formula:

• Acceleration = (15 m/s - 0 m/s) / 3 s
• = 15 m/s / 3 s
• = 5 m/s²

Therefore, the acceleration of the car going from stationary to a speed of 15 m/s in 3 seconds is 5 m/s².
