Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.

Q1. 1) The missile at point A takes off from rest and rises vertically to point B after 6.7 seconds, where its fuel runs out. During this time the acceleration of the missile is a = (C.t) m/s², where C = 3.4 is a constant and tis time in s. (Hint, this expression of acceleration already takes into consideration of gravity.) Then by internal controls the missile tilts to an angle = 40° as shown, while keeping the speed, vg, it has attained, and from there it travels in free flight until it lands on the ground at point D. Determine the missile's height he (in m) at point B. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s². C B hB hc R- D
