The force (in newton) applied to an object varies jointly as its mass and acceleration. How much force is needed to accelerate a 25 kg object by 4 m/s2?a. 50 b. 75 c. 100 d. 125

Respuesta :

We will have the following:

[tex]\begin{gathered} F=ma \\ \\ \Rightarrow F=(25kg)(4m/s^2)\Rightarrow F=100N \end{gathered}[/tex]

So, the force needed is 100N.
