A train is moving at 65.0 m/s. After 16.0 seconds, it is moving at 85.0 m/s. What is the acceleration?
den301095 [7]

Happy Holidays!

We can use the following equation to calculate uniform acceleration:

\large\boxed{a = \frac{\Delta v}{\Delta t} = \frac{v_f - v_i}{\Delta t}}}

Plug in the given values to solve:

\frac{85 - 65}{16}}} = \frac{20}{16} = \boxed{1.25 m/s^2}}
