Q 7.1: Two ice skaters with masses of 40 kg and 60 kg stand together on frictionless ice. The first skater pushes against the second. When the first skater has moved a distance of 12 m, how far has the second skater moved

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
