Textbook Question
Chapter 15, Problem 3RAT
Which would you expect to have a higher melting point: sodium chloride, NaCl, or aluminum oxide, Al2O3?
(a) Aluminum oxide, because it is a larger molecule and has a greater number of molecular interactions
(b) NaCl, because it is a solid at room temperature
(c) Aluminum oxide, because of the greater charges of the ions and hence the greater force of attraction between them
(d) Aluminum oxide, because of the covalent bonds within the molecule

- Part C Find the height yi from which the rock was launched. Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g.
