Tom is climbing a 3.0-m-long ladder that leans against a vertical wall, contacting the wall 2.1 m above the ground. his weight of 880 n is a vector pointing vertically downward. (weight is measured in newtons, abbreviated n.)
a) what is the magnitude of the component of tom's weight parallel to the ladder?
b) what is the magnitude of the component of tom's weight perpendicular to the ladder?

A)

B)

Explanation:

Given:

Length of the ladder

weight of the Tom  

The angle that ladder make with x axis is

Part A

magnitude of the component of the weight parallel to the ladder

Part B)

The magnitude of the component of Tom's weight perpendicular to the ladder

e) none of the above answers are correct

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
