AI A regulation basketball has a 21 cm diameter and
may be approximated as a thin spherical shell.
How long will it take a basketball starting from
rest to roll without slipping 4.1 m down an incline
that makes an angle of 11.6° with the horizontal?
The acceleration of gravity is 9.81m/s2.
Answer in units of s.

see earlier

because if the tool that you are using is not balanced it there would be false mass.

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
