Answer:
14185.5J
Explanation:
Thermal energy can be calculated using the formula
Q = mcT where
Q is the amount of thermal energy in <em>J</em>
m is the mass in kg
c is the specific heat capacity in <em>J/kg/C</em>
T is the change in Temperature in <em>C</em>.
Hence by applying this formula, we get:
Q = (0.175)(4200)(24.3 - 5.00)
<u>Q = 14185.5 J</u>

The first thing you should do in this case is to realize that you have two different materials.
First we make a free body diagram.
Then, we use the definitions of mechanics to find the forces.
Finally we substitute the values to find the normal stress due to the load.
Solution attached.
True, all motions are related to inclined planes.
Initially, mg = kx. K = mg/x = 700/0.5x10^-3 = 1400000N/m. From second condition, applying work-energy theorem, potential enery- elastic potential energy = change in kinetic energy. Now change in kinetic energy is 0 since initial and final velocities are 0m/s. Therefore, potential energy = elastic potential energy. mgh = (1/2) * k* x^2. x^2 = 2(mg)h/k = 2 x 700 x 1.3/ 1400000. x = 0.036m. Hope it's clear.
