Draw additional masses to show how the block can be made to move toward point a. be sure to draw the string and label the mass of the block. for full credit, draw the minimum number of blocks required to make the block move toward point a.

an electric circuit

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
