Answer:
Velocity of the grip A= 24.077 ft/sec ,at t=3 seconds
Acceleration of the grip A=8.2764 ft/sec^2, at t=3 seconds
We have that the <em>temperature </em>at the <em>interface </em>of the two <em>layers</em>, in °F, and (b) the rate of heat transfer through the wall in Btu/h*ft^2 of surface area is given as
a)
b)
From the question we are told
A composite plane wall cons<em>i</em>sts of a 5-in.-thick layer of insulation (ks = 0.029 Btu/h*ft*°R) and a 0.75-in.-thick layer of siding (ks = 0.058 Btu/h*ft*°R).
The inner temperature of the insulation is 67°F. The outer temperature of the siding is -8°F.
<h3>Interface Temperature</h3>Generally the equation for the Terminal resistance is mathematically given as
b)
a)Interface Temp(T_i)

Explanation:
<u>To derive the equation we have to make some assumptions </u>
assumptions:
Assume T depends on Z alone
Assume uniform thermal and electrical conductivities (k and ke) in the wire, Assume a uniform heat
transfer coefficient h from the wire to the air stream.
attached below is the required derivation of the equation
