Suppose you are in an elevator that is moving upward. as the elevator nears the floor at which you will get off, its speed slows down. during this time when the elevator is moving upward with decreasing speed, your weight will be

Less than your normal weight at rest

Explanation:

When the elevator is moving upwards with decreasing speed it means that the elevator is decelerating, thus the weight is lower than normal even though you are being pulled down with gravity acceleration.However, remember that your normal force is equal to your weight when the elevator is accelerating upwards,  you feel a little heavier than usual and a little litter if the elevator is accelerating downwards.

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
