Three forces are being exerted on a common object. Two of the forces are acting downward with values of 20 N and 45 N respectively. The third force (15 N) is being exerted upward
on the same object. What should the magnitude and direction of the net force acting on the
object be? Include a free body diagram.

its a 5.5 n

glad that

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
