Answer:
large balloon
Explanation:
Thermal energy is the amount of energy contained in a system solely by the effect of its temperature. However, this concept should not be confused with that of internal energy. Internal energy, in turn, is defined as the sum of kinetic energy (translational, rotational and vibrational) with the different forms of potential energy (attractive or repulsive) that can exist between the molecules of a body.
Kinetic energy is associated with the movement of molecules, while potential energy is energy that can be stored in a physical system. In the case of balloons filled with air or liquids, the larger the balloon, the greater the kinetic potential and consequently the thermal energy. For example, a large balloon filled with air will have more thermal energy, because it will have more air molecules that will move through the kinetic energy causing thermal energy.
No, the rope would not be strong enough to tow the car since the tension of the rope is less than weight of the car.
The tension in the rope must equal the weight of the supported mass. In this case, the weight of the car is 14,000 N, which is greater than the tension the rope can withstand (12,000 N).
Therefore, this rope would not be strong enough to tow the car. It would require a tension strength of at least 14,000 N.

initial height of the pole vaulter = 4.2 m
height of the pole vaulter just before it touch the pad = 80 cm
so the total displacement of pole vaulter just before he will touch the pad = 4.2 - 0.80 = 3.4 m
now by kinematics
now after this he will come to rest after compressing the pad by 50 cm
so again we can use kinematics to find its acceleration
so here its acceleration will be - 66.64 m/s^2
