A 1.70 kg block rests on the icy surface of a frozen pond, which you can assume to be frictionless. If the location of the block is measured to a precision of 0.30 cm, what is the minimum uncertainty in the block's speed, assuming the mass is known exactly?
The Attempt at a Solution
I plugged in all the values and got v. The answer was wrong. I then multiplies by .0003 and that was also wrong.
