The angular momentum of the propellers of a small airplane points directly forward from the plane. (a) in what direction do the propellers rotate as seen from the rear of the plane? (b) if the plane is flying horizontally and suddenly pulls upward, in which direction does the nose of the plane tend to move? justify your answer.

which three statements are true about all alloys?

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

the answer should be in the picture.
