Answer:

mass = 20.408 kg

Step-by-step explanation:

Formula: GPE = mgh

Solve:

600 = m*9.8*3

600 = m*29.4

m= 600/29.4

m= 20.408 kg

Result:

20.408 kg

Answer: 20kg

Explanation: the above question is base on workdone...

Note: work done is also equal to potential energy.

➡Mathematical expression for the above statement:

W = P.E. where w and p.e are noted to be work done and potential energy...

Therefore; P.E = mgh

Where m is the mass of the object, g is the acceleration due to gravity and finally h is the height...

Therefore; P.E = mgh

600 = m x 10 x 3

600 = 30m

Divide both side by the coefficient of m

Therefore; 600/30 = m

m = 20kg
