###### Question:

A vertical spring (ignore its mass), whose spring constant is 875 N/m , is attached to a table and is compressed down by 0.160 m.

A) What upward speed can it give to a 0.320-kg ball when released?

I tried 7.88 m/s, but it said "Review your calculations; you may have made a rounding error or used the wrong number of significant figures." What would the correct answer be? It wants it in 3 sig figs.

B) How high above its original position (spring compressed) will the ball fly?
