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]
