Hello
Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy
the formula to use is

where m is the mass of the object and v the velocity
lets see the kinetic energy of the sprinter running

Now, the elephant must have the same kinetic energy

it works only the positive root, so the elephant must to walk to 1.4719 m/s to have the same kinetic energy.
Have a great day
Answer:
the work done by a person is 1,732 J
Explanation:
The computation of the work done by a person is as follows;
The following information is given
Force = 200.N
Distance = 10.0 meters
Angle = 30 degrees
based on the above information
Work done is

Work done is
= (200) (cos 30 degrees) (10.0 meters)
= 1,732 J
hence, the work done by a person is 1,732 J
The same is considered and relevant
