Answer:
Normal force, N = 154.5 N
Explanation:
Given that,
Total mass of the cart, m = 20.4 kg
Angle of inclination,
Distance moved, d = 20.1 m
The coefficient of kinetic friction between ground and cart is 0.6
The value of acceleration due to gravity,
Let N is the normal force exerted on the cart by the floor. It is given by :
T = 103.23 N
So, the normal force is :
N = 154.5 N
So, the normal force exerted on the cart by the floor is 154.5 N. Hence, this is the required solution.
From the definition of entropy, the entropy change of an object is
where
Q is the heat absorbed
T is the absolute temperature
in our problem, we have Q=25.0 J, while the absolute temperature is (converting in Kelvin)
and so the entropy change is
