Answer
a) $58.3km$
b) $68.534 s$
c) $2.55 kN$
d) $7.56 Mg$
Work Step by Step
We are given a few quantities that we will convert to an appropriate SI unit. We are asked to record each answer to three significant digits, so in our final answer we will round our final answer and record the first three digits.
a) $58342 m * \frac{1km}{1000m}= 58.342km \approx 58.3km $
b) $68.534 \approx 68.5s$
c) $2553 N*\frac{1kN}{1000N}=2.553 kN \approx 2.55kN$
d) $ 7555 kg*\frac{1Mg}{1000kg}=7.555 Mg \approx 7.56Mg$
