Kinetic energy is energy of motion. The kinetic energy of an object is dependent on two variables, speed and mass and can be represented by the formula:
KE = 1/2mv2
Sammie is speeding done the road in his race car. Sammie passes one car after another. Sammie has more kinetic energy than the
cars he is passing. He pulls up to a BIG truck and the two are traveling neck and neck down the highway. Is there any difference in
the kinetic energy of the truck and Sammie's car? Explain.

the answer is 75.0%.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
