Chapter 8.1, Problem 8.1CE

Comet Halley’s Orbital Parameters

Figure 8.1 shows Comet Halley’s elliptical orbit.

a. Use the information given in the case study above and Kepler’s third law from Chapter 7 to find the semimajor axis a of Comet Halley’s orbit.
b. The comet’s perihelion distance is r_P = 0.59 AU. Find its aphelion distance (farthest point from the Sun).

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. Thus, the problem becomes one of…
