12. A 50kg and 40kg man climbed a coconut tree with a height of 15m. Compare the potential energy of each man. A. The potential energy of each man is 7,350J and 5,880J. B. The potential energy of a 50kg man is 7,350J that is greater compared to a 5,880J potential energy of a 40kg man. C. The potential energy of 50kg and 40kg man who climbed a height of 15m are 7,350J and 5,880J respectively. D. The potential energy of a 50kg man is 7,350J that is greater compared to a 5,880J potential energy of a 40kg man thus the greater the mass of a body the greater the potential energy.

13. What is kinetic energy?
A. Kinetic energy is the energy in motion.
B. Kinetic Energy is the energy possessed by a moving object.
C. Kinetic energy is the energy in motion, and it is expressed in Joule.
D. Kinetic energy is the energy in motion, and it depends on the mass
and velocity of the object.
14. Two cars A and B are travelling at a velocity of 10m/s and 20m/s
respectively. If both cars have the same mass, which car will have a greater
kinetic energy? Why?
A. Car B
B. Car B has a greater kinetic energy compared to Car A.
C. Car B has a greater kinetic energy compared to Car A due to its
velocity.
D. Car B has a greater kinetic energy compared to Car A because the
faster the body move the greater the kinetic energy.
15. Two identical objects with a mass of 3kg each are travelling at a velocity of
Sm/s and 10m/s. What is the kinetic energy possessed of each object?
A. The kinetic energy of the objects are 37.5J and 150J.
B. The kinetic energy of two identical object travelling at a velocity of
5m/s and 10m/s are 37.5J and 150J respectively.
C. The kinetic energy of an object travelling at velocity of 5m/s is 37.5J
that is lesser compared to 150J kinetic energy of an object travelling
at a velocity of 10m/s.
D. The kinetic energy of two identical object travelling at a velocity of
5m/s and 10m/s are 37.5J and 150J respectively thus the kinetic
energy of the second object is four times the value of the kinetic
energy of the first object due to its velocity.
