Final answer:
The potential energy of the lady Spartan at the top of her jump is 294 Joules.
Step-by-step explanation:
The potential energy of an object at the top of its jump can be calculated using the formula PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height from which the object falls.
In this case, the lady Spartan's potential energy at the top of her jump can be calculated as follows:
PE = (60 kg) * (9.8 m/s^2) * (0.5 m)
PE = 294 J
So, the lady Spartan had 294 Joules of potential energy at the top of her jump.
