A body is thrown vertically upward from the earth's surface de l
to its original position Find out the initial velocity with which it was thrown up (The
resistance is considered as zero
the car driver saw a child on the

terd muffin is the correct answer

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
