5. A student dribbles his soccer ball down the hallway before practice. He dribbles it with a force of 7N for 13m with 1.75N of friction from the carpet acting on it. What is the soccer balls final kinetic energy?

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

did yall get answers for this yet
