In practice, there may be a systematic error in this experiment because of Page 14 of 51
THE E
friction in the pulleys.
When the measurements were taken, increasing values of m were used. State
and explain how friction in the pulleys would have affected the measured
values of y.

answera compound;

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
