Question

4. An object moving with a constant velocity has an unbalanced force applied to it.If the unbalanced force is -20.0 N and the mass of the object is 3.75 kg, what is theacceleration of the object while this force is acting?

Answer 1

The acceleration of the object due to unbalanced force can be given as,

`a=(F)/(m)`

Substitute the known values,

`\begin{gathered} a=\frac{-20.0\text{ N}}{3.75\text{ kg}}(\frac{1kgm/s^2}{1\text{ N}}) \\ =-5.33m/s^2 \end{gathered}`

Thus, the acceleration of the object is -5.33 m/s^2.
