To lift a heavy crate, a man uses a block and tackle attached to the bottom of an i-beam at hook b. knowing that the moments about the y and the z axes of the force exerted at b by portion ab of the rope are, respectively, 120 n·m and –460 n·m, determine the distance a, which is the distance from the y axis to the hook b.

scientific laws are the result of testing theories and proving them to be facts.

thermal energy is the 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

no

explanation:

no i dont know how to solve this you should probably try to google the answer
