Question

A fuzzy die that has a weight of 1.80 N hangs from the ceiling of a car by a massless string. The car travels on a horizontal road and has an acceleration of 2.80 m/s2 to the left. The string makes an angle?

Answer 1

The string makes 15.9° angle.

Step-by-step explanation:

Given that,

Weight of car = 1.80 N

Acceleration = 2.80 m/s²

We need to calculate the string makes an angle

Using formula of angle

`\tan\theta=(ma)/(mg)`

`\theta=\tan^(-1)((a)/(g))`

Where, a = acceleration

g = acceleration due to gravity

Put the value into the formula

`\theta=\tan^(-1)((2.80)/(9.8))`

`\theta=15.9^(\circ)`

Hence, The string makes 15.9° angle.
