After reading about gravity, Paolo tests his hypothesis that a feather and a marble will fall at the same rate. If the marble falls faster, what should Paolo do next?
A. Decide that the hypothesis is useless because it made an
incorrect prediction
B. Report that the results of the experiment were wrong
C. Conclude that his science textbook was mistaken about gravity
D. Look for other factors that affect how fast something falls

the area between the graph and the t axis

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
