Lucy lightfoot stands with one foot on one bathroom scale and her other foot on a second bathroom scale. each scale reads 380 n .what is lucy's weight?

760 N

Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.

When Lucy stands on the weighing scale, net force due to gravity is

Hence, weight of Lucy is 760 N

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
