Question
A car that had been traveling at 28m/s slams on the brakes. As the car slows to a stop at a uniform rate, a block hanging from a string attached to the rearview mirror tilts so it makes an angle with the vertical of θ=36. What is the magnitude of the acceleration of the car while stopping?

a / g = tan(θ)
a = tan(36º) * 9.8 m/s^2
a = tan(36º) * 9.8 m/s^2
