A force of 2500 N acts on a car of mass 1000 kg - Leaving Cert Physics - Question (b) - 2019

To calculate the acceleration of the car, we can use Newton's second law of motion, which states:

$F = m \cdot a$

Where:

• $F$ is the force applied (in Newtons),
• $m$ is the mass of the object (in kilograms), and
• $a$ is the acceleration (in meters per second squared).

Given:

• $F = 2500 \text{ N}$
• $m = 1000 \text{ kg}$

We can rearrange the formula to solve for acceleration:

$a = \frac{F}{m}$

Substituting the given values into the equation gives:

$a = \frac{2500 \text{ N}}{1000 \text{ kg}}$

Calculating this yields:

$a = 2.5 \text{ m/s}^2$

Therefore, the acceleration of the car is 2.5 m/s².
