02 Multiple Choice A disk is mounted horizontally on an axle and is free to rotate around that axle. A force is going to be applied in the same plane as
the disk to generate a torque on the disk. In order to get the highest angular acceleration possible, where and how should that force
be applied?
A. Halfway between the axle and the edge, perpendicular to the edge (toward the axis)
B. at the edge but not tangentially or perpendicularly
C. Halfway between the axle and the edge tangentially
at the edge perpendicular to the edge (toward the axis)
D. At the edge tangentially

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

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

the tires are rotating at 0.434 rpmlinear speed=45 m/sdiameter=0.550 mradius=0.275 mnow v= rωω= v/rω=45/0.275ω=163.6 rad/sω=163.6 rad/s (1rev/2π rad) (60s/1m)ω=1563 rpm

i think the answer is bone
