5.72 m/s^2 First, we have available 2 conversion units. 5.24 flurg/m and 0.493 s/grom I chose the units to describe those two conversions by making the denominator equal to 1 in both cases, so there are 5.24 flurgs per meter and 0.493 seconds per grom. Now we've been given 7.29 flurg/grom^2 and we want to convert to m/s^2. So we need to figure out how to multiply or divide our conversion factors to cancel out the flurg and grom units. Let's see about cancelling the flurg unit 1st and replacing it with meters Let's try multiplication flurg/grom^2 * flurg/m = flurg^2/(m*grom^2) That won't work. So let's try division flurg/grom^2 / flurg/m = flurg/grom^2 * m/flurg = (m*flurg)/(grom^2 * flurg) The flurg on top and bottom, cancel, so = m/grom^2 So dividing by our length conversion will work correctly. Let's do it. 7.29 flurg/grom^2 / 5.24 flurg/m = 1.391221374 m/grom^2 Now we want to convert from m/grom^2 to m/(s grom) using our time conversion factor. Since we want s in the denominator and it's in the numerator, a division looks good. So m/grom^2 / s/grom = m/grom^2 * grom/s = (m*grom)/(grom^2 * s) = m/(grom * s) And it is good. So let's do it 1.391221374 m/grom^2 / 0.493 s/grom = 2.821950049 m/(grom s) We still have one more grom to get rid of. And since it's in the same place as the previous one, let's divide again. 2.821950049 m/(grom s) / 0.493 s/grom = 5.72403661 m/s^2 Since all our input is to only 3 significant figures, round the result to 3 significant figures.
