The distance from the dwarf planet pluto to the sun is 4.43 × 109 km at perihelion and 7.37 × 109 km at aphelion. find the eccentricity e of pluto's orbit. (round your answer to three decimal places.) e =

i think they are all correct

explanation:

they seem good

the answer is a. hope this .

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
