Question

How much force is needed to accelerate a 2500 kg car at a rate of 4m/s2?7,500 N8,400 N10,000 N625 N

Answer 1

Given:

The mass of the car is,

$m=2500\text{ kg}$

The acceleration of the car is,

$a=4\text{ m/s}^2$

To find:

The necessary force

Explanation:

The necessary force is,

$\begin{gathered} F=ma \\ =2500\times4 \\ =10000\text{ N} \end{gathered}$

Hence, the required force is 10000 N.
