True because it have a lot of energy at the top because of gravity and air restrictsence
Time = 13.5 / 2.5 = 5.4 seconds
Answer:
Explanation:
from the question we are told that
Load 
Force
Angle of inclination 
Displacement 
coefficient of kinetic friction 
The potential energy is most often referred to as the "energy at rest" and is dependent on the elevation of an object. This can be calculated through the equation,
E = mgh
where E is the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height. In this item, we are not given with the mass of the cart so we assume it to be m. The force is therefore,
E = m(9.8 m/s²)(0.5 m) = 4.9m
Hence, the potential energy is equal to 4.9m.
