An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0Ā° above the horizontal. it then moves 127 ft at an angle of 46.0Ā° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4Ć10 to the power of 23 kg, radius = 3.4Ć10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3Ć10 to the power of 8 km from the sun.)
