Answer:
- [tex]2\frac{m}{s^2} =a[/tex]
Explanation:
Use the kinematic equation.
- [tex]v_{2} =v_{1} +at[/tex]
This equation can be derived from [tex]f=ma[/tex], but we can just memorize, or look them up when needed as it saves us time.
Now we can plug our measurements into each variable to solve for acceleration.
- [tex]18\frac{m}{s} =8\frac{m}{s} +a*5s[/tex]
Subtract 8m/s from both sides.
- [tex]10\frac{m}{s} =a*5s[/tex]
Divide by 5 seconds. Left with acceleration in terms of [tex]\frac{m}{s^2}[/tex]
- [tex]2\frac{m}{s^2} =a[/tex]
