Answer:
The answer is the 4th one
Explanation:
Good luck man
First calculate the time it would take for the crate to
fall using the formula:
h = v0 t + 0.5 g t^2
110 m = 0 + 0.5 (9.8 m/s^2) t^2
t = 4.74 s
The crate is also moving at 46 m/s on with respect to the
horizontal surface, therefore distance covered is:
d = (46 m/s) * 4.74 s
d = 217.95 m
The crate would fall 217.95 m from the tail of the car.
The changes in internal energy of the system <u>75.1 J.</u>
The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.
Calculation:
Internal energy = 162.4 j - work done
= 162.4 j - 87.3 j
=<u> 75.1 J</u>

Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.
Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.
