Answer:
[tex]\displaystyle v = 12.4134 \ m/s[/tex]
General Formulas and Concepts:
Energy
Kinetic Energy Formula: [tex]\displaystyle KE = \frac{1}{2}mv^2[/tex]
- m is mass (in kg)
- v is velocity (in m/s)
Explanation:
Step 1: Define
Identify variables.
KE = 7250 J
m= 94.1 kg
Step 2: Solve for v
- Substitute in variables [Kinetic Energy Formula]: [tex]\displaystyle 7250 = \frac{1}{2}(94.1)v^2[/tex]
- Isolate v term: [tex]\displaystyle 154.091 = v^2[/tex]
- Isolate v: [tex]\displaystyle v = 12.4134[/tex]
