Chapter 8, Problem 1PLA

To determine

The acceleration of the object.

Answer to Problem 1PLA

The acceleration of the object is $3.85\text{m}/{\text{s}}^{\text{2}}$.

Explanation of Solution

Write the formula to find the force using Newton’s second law

    $F=ma$

Here, $F$ is the force exerted on the mass, $m$ is the mass and $a$ is the acceleration.

Rearrange the above equation and solve for $a$

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

Substitute $25.0\text{ N}$ for $F$ and $6.50\text{ kg}$ for $m$ in the above equation to find the value of $a$

$\begin{array}{c}a=\frac{25.0\text{ N}}{6.50\text{ kg}}\\ =3.85\text{m}/{\text{s}}^{\text{2}}\end{array}$

Conclusion:

Thus, the acceleration of the object is $3.85\text{m}/{\text{s}}^{\text{2}}$.
