Lightsail-2 is a spacecraft launched in june 2019 by the planetary society driven by radiation pressure on a solar sail of area 30 square meters. it is currently in low earth orbit. given the solar constant (solar power at the earth’s surface) 1,388 w/m2 , estimate the force on the sail if it is oriented so that the solar radiation strikes the sail perpendicularly. assume the sun emits pure yellow light of wavelength 570 nm, and that each photon is specularly reflected, with no absorption. (a) (5 pts) how many yellow photons hit the sail per second? (b) (5 pts) what is the force imparted to the sail?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° 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.)
