Answer:
a = 22.22 m/s^2
Explanation:
Equation to use:
[tex]v_{f} = v_{i} + at\\[/tex]
Knowns:
[tex]v_{f} = 1000m/s\\t = 45s[/tex]
Solving for:
[tex]a = ?[/tex]
Rearrange to solve for acceleration.
[tex]\frac{v_{f} -v_{i} }{t} = a[/tex]
Plug in known values and solve.
[tex]\frac{1000-0}{45} = a \\a = 22.22[/tex]
Don't forget the units.
a = 22.22m/s^2
