Answer:

50kg

Step-by-step explanation:

Using the formula for potential energy, which is the amount of energy due to position;

P.E = m × g × h

Where;

m = mass (kg)

g = acceleration due to gravity (10m/s²)

h = height (metres)

According to the information provided in this question, m = ?, P.E = 2500J, h = 5m

Using P.E = m × g × h

m = P.E/gh

m = 2500/(5 × 10)

m = 2500/50

m = 50kg

The mass of the man is 50kg.
