The weightlifter's power output is 170 watts.

To calculate the power output, we can use the formula:

Power (P) = Work (W) / Time (t)

In this case, the work done is 850 J and the time taken is 5 s.

Substituting the values into the formula, we get:

Power (P) = 850 J / 5 s = 170 W

Therefore, the weightlifter's power output is 170 watts.
