Answer:
Jim's kinetic energy is 54.67 J.
Explanation:
Given that,
Mass, m = 15 kg
Velocity, V = 2.7 m/s
We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :
E = 54.67 J
So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
Hydroelectricity is the best answer.

Electric force from electomagnetic force and force of gravity from gravitational force
The answer is c because:
Work done =force x distance
The gravitational force is 1.98×10^20 m.
Computation of gravitational force:
The gravitational force F between two masses is given by the formula,
F=Gm1m2/ r^2
where G is the gravitational constant.
Note: It is assumed m1=5.972×10^24 kg, m2=7.348×10^22 kg and r=3.84×10^8 m and G=6.67×10^(-11) N m^2 kg^-2
Then F=(6.67×10^(-11)×5.972×10^(24)×7.348×10^(22))/ (3.84×10^8)
F=1.98×10^(20) N
