Imagine that scientists of the future launch a large chunk of positively-charged matter into space towards the sun. After a long time, researchers notice that the chunk of matter has gone into orbit around the sun instead of flying past the sun and continuing on its way. Which statement best explains this phenomenon?

the part of the wave he is travelling on is the crest

cancer risk 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
