Name two of the four common boundry conditions we set when disucssing gravitational potential energy?

Explanation:A raised weight.

Water that is behind a dam.

A car that is parked at the top of a hill.

A snow pack (potential avalanche)

A yoyo before it is released.

River water at the top of a waterfall.

A book on a table before it falls.

A child at the top of a slide.

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
