what is the next step if the data from an investigation do not support the original hypothesis?

The experiment can perform again to revise the data.

Explanation:

The hypothesis can be defined as the explanations or suppositions that are acceptable  in order to prove some natural phenomena by the help of experimental procedure.

And the condition is occur which suggest that the data which you get from the experiment do not supported hypothesis that is given originally, then the experiment or investigation should be perform again.

Therefore, if the data is incorrect then we have to perform that experiment again to gather a data which is correlated with the original hypothesis.

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
