Step-by-step explanation:
Given that,
Mass of Ella is 56 kg and mass of Tyrone is 68 kg.
Position of Ella is 1.5 m on the ramp.
Potential energy of an object is given by :
P = mgh
It is directly proportional to the position of an object.
If Tyrone stands at the top of ramp at more height than Ella, it will have more potential energy. Hence, the correct option is (d) "If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's."
