Apackage is dropped from the plane which is flying with a constant horizontal velocity of va = 150 ft/s. determine the normal and tangential components of acceleration and the radius of curvature of the path of motion (a) at the moment the package is released at a, where it has a horizontal velocity va = 150 ft/s, and (b) just before it strikes the ground at b.

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

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

i would think it's food chain
