Here's how I tried to solve it.

Solve for acceleration, which I assumed was constant.

Code:

`a = F/m = 5N / 2kg = 2.5 m/s/s`

Then use the displacement equation to find the distance traveled.

Code:

```
x = xo + (vo)(t) + (1/2)(a)(t^2)
x = 0 + 0 + (1/2)(2.5 m/s/s)(2s)^2
x = 5m
Work = F * x = 5N * 5m = 25 J
Power = Work / t = 25J / 2s = 12.5 W
```

a) 5W b) 10W c) 25W d) 50W e) 75W

Where am I screwing up?
