A little

souvenir vicuña figurine with a mass of m = 50 g hangs by a thin
string from the rear view mirror of your car. As you accelerate,
you notice that the string makes an angle of 10.0° from the

Answer 1

Hanging things from rear view mirror is illegal in some states

Let T be tension in string

T cos θ = M g tension due to weight

T sin θ = M a tension accelerating weight

tan θ = a / g

a = g tan 10.0 = .176 g = .176 * 9.8 m/s^2 = 1.73 m/s^2
