Answer :

Answer:

The change in velocity was about [tex]9.84~\text{m/s}[/tex]

Explanation:

Step 1: Understand which formulas to use

The problem has the quantities: mass, force, time and change in velocity, and they are all already in their standard form/

We know that change in velocity divided by time equals to acceleration:

[tex]a=\frac{v-v_{0}}{t}[/tex]

Another formula that involves acceleration, mass and force is:

[tex]F=m\times a[/tex]

Step 2: Do the calculations:

The time is said to be [tex]8.3~\text{s}[/tex], so the acceleration will be:

[tex]a=\frac{v-v_{0}}{8.3}[/tex]

Substitute this value and the value for force, mass into the other formula:

[tex]F=m\times a\\115=97\times \frac{v-v_{0}}{8.3}[/tex]

[tex]v-v_{0}[/tex] denotes the change in velocity, so we will have to make it the subject.

[tex]115=97\times \frac{v-v_{0}}{8.3}\\\\\frac{115}{97}=\frac{v-v_{0}}{8.3}\\\\\frac{115}{97}\times 8.3 =v-v_{0}\\\\v-v_{0}\approx 9.84[/tex]

Thanks for taking the time to read If a 97 kg object is subjected to 115 N of force for 8 3 seconds what is the change in velocity.
