Answer:

m = 50 [kg]

Explanation:

The potential energy can be calculated by means of the following equation.

[tex]E_{p}=m*g*h[/tex]

where:

Ep = potential energy = 735 [J]

m = mass [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation = 1.5 [m]

Now replacing:

[tex]735=m*9.81*1.5\\m = 50 [kg][/tex]
