Janet and Amold balance on a see-saw as shown in the image below. If Janet is sitting 1.8 m from the axis of rotation, how far from the axis of rotation is Arnold? ( picture not drawn to scale)

PLS HELP IM CONFUSED

the answer is kevlar

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

a. are

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
