What are the factors of the meteorite or asteroid that affect the size of an 2 points impact crater?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

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
