- Need to show all of the work and correct units5. For most automobiles, the number of miles per gallon decreases as highway speed increases. Fuel economy drops as speeds increase from 55 to 65 mph, then decreases further as speeds increase to 75 mph. Explain why this is the case. Please state the following (apply your problem solving strategy): A. REASON: State and describe the overall physical principles you think apply to solve this problem. 3. ASSESS: What is the energy content in kJ of gasoline in 1 g of fuel?Vector A→ is in the direction 29.0 ∘ clockwise from the -y-axis. The x-component of A→ is Ax = -12.0 m. - what is the y-component of A→ with appropriate units? - what is the magnitude of A→ with appropriate units? ------------------------------------------------------------------------------ above is the question that I am struggling on for my physics w/ cal I class. My brain tells me (for the first question about the component) that I have to add 270 to 29 (because of the -y axis) to get Ay = -12.0m(sin(299)) to get ~10.50 m but when I insert the answer I get, its wrong.
