Question

Evaluate each of the following to three significant figures and express each answer in SI units using an appropriate prefix: (a) (3396 μm)/(24 ms), (b) (26 mm)(0.058 Mg)/(140 ms2), (c) (2.35 mm.g)(131 s). (Note: mm.g means mm “dot” g)

Expert Solution

Step 1

(a)

$\frac{3396 μm}{24 ms} = \frac{3396 \times 10^{- 6}}{24 \times 10^{- 3}} m / s = 0.1415 m / s$

(b)

$\frac{(26 mm) (0.058 Mg)}{140 m \cdot s^{2}} = \frac{(26 \times 10^{- 3} m) (0.058 \times 10^{3} kg)}{140 m \cdot s^{2}} = 0.0010 kg / s^{2}$
