A0.12-kg softball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. what is the change in the magnitude of the momentum of the softball?

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
