**1. Homework Statement**

A car acclerates down a hill, going from rest to 22.0m/s in 9.00s. During the acceleration, an object (m=.400kg) hangs by a string from the car's ceiling. The acceleration is such that the string remains perpendicular to the ceiling

Find the angle and the tension in the string

**2. Homework Equations**

**3. The Attempt at a Solution**

Could I use these equations?

a=m2gsinθ-m1g/m1+m2

T=m1m2(sinθ+1)/m1+m2

Thank you very much
