D and E A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A = 6.80 x 105 m2and mass m = 5,900 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2.(a) What force (in N) is exerted on the sail? (Enter the magnitude.)6.21(b) What is the sail's acceleration? (Enter the magnitude in um/s?.)1052.54v um/s2(c) Assuming the acceleration calculated in part (b) remains constant, find the time interval (in days) required for the sail to reach the Moon, 3.84 x 108 m away, starting from rest at the Earth.9.89v days(d) What If? If the solar sail were initially in Earth orbit at an altitude of 380 km, show that a sail of this mass density could not escape Earth's gravitational pull regardless of size. (Calculate the magnitude ofthe gravitational field in m/s?.)x m/s2(e) What would the mass density (in kg/m2) of the solar sail have to be for the solar sail to attain the same initial acceleration as that in part (b)?kg/m2

Given that: m=5900 kg A=6.80x105 m2 I=1370 W/m2 h=380 km R=6371 km
