Answer

Please see the work below.

Work Step by Step

We know that $h=\frac{v^2}{2g}$ The above equation shows that height is inversely proportional to g $\implies h_{mars}=(\frac{g_{earth}}{g_{mars}})h_{earth}$ We plug in the known values to obtain: $h_{mars}=(\frac{9.81}{3.74})(2.45)$ $h_{mars}=6.43m$ (b) We know that $\implies h_{moon}=(\frac{g_{earth}}{g_{moon}})h_{earth}$ We plug in the known values to obtain: $h_{moon}=(\frac{9.81}{1.62})(2.45)$ $h_{moon}=14.8m$
