Answer:
Lastly, the heat transfer rate depends on the material properties described by the coefficient of thermal conductivity. All four factors are included in a simple equation that was deduced from and is confirmed by experiments. The rate of conductive heat transfer through a slab of material, such as the one in Figure 3, is given by

where

t
is the rate of heat transfer in watts or kilocalories per second, k is the thermal conductivity of the material, A and d are its surface area and thickness, as shown in Figure 3, and (T2 − T1) is the temperature difference across the slab. Table 1 gives representative values of thermal conductivity.
Explanation:
In the x-direction, the frictional force is the lone force pro
tem on the player
The formula is: Fnet = ma
f = ma
In the y-direction, N, the normal force turns up and mg, the force of gravity turns
down
N = mg (since there is no speeding up in the vertical direction)
f = -uN
=> f = -umg
-umg = ma
=> a = -ug
Using the kinematics equation:
d = (vf^2 - vi^2) / 2a
d = vi^2 / 2ug
d = 4.6^2 / 2(4.508)
d = 2.35 m/s
Explanation:
Time is the rate at which a distance traveled at a given period
