SOMEONE ASKED ๐
An object is hanging by a string from your rearview mirror.?
HERE THE ANSWERS ๐

Horizontal components of the forces are as follows:
T(sin ฮ) = ma โ call this Equation 1
and the vertical components of the forces are
T(cos ฮ) = mg โ call this Equation 2
where
T = tension in the string
ฮ = angle that string makes with the vertical
m = mass of the object
a = acceleration = 25/5.7 = 4.386 m/sec^2
g = acceleration due to gravity = 9.8 m/sec^2 (constant)
Dividing Equation 1 with Equation 2,
T(sin ฮ)/T(cos ฮ) = ma/mg
and simplifying the above,
tan ฮ = 4.386/9.8
tan ฮ = 0.4475
ฮ = arc tan 0.4475
ฮ = 24.1 degrees
Hope this helps.
