Answer:

The force needed to lift the crate is 50 N

Explanation:

[tex]P_{1} = \frac{F_{1}}{A_{1}} = \frac{1500N}{25 m^{2} } \\P_{1}= P_{2} \\P_{2} = \frac{F_{2}}{A_{2}}\\A_{2} = 25*\frac{1}{30} \\\frac{1500N}{25 m^{2} } =\frac{F_{2} }{\frac{25}{30}m^{2}  }\\ F_{2}* 25 m^{2} = 1500 N *\frac{25}{30}m^{2}\\ F_{2}= \frac{1250 N*m^{2}}{25 m^{2}}\\ F_{2}= 50 N[/tex]
