Asked by Suhindar
You have a 0.35 long pendulum attached to the roof inside your car. Your car is travelling at a speed of 1.0 m/s when it hits a concrete wall and stops immediately. If the pendulum is free to swing, to what maximum angle to the vertical does the pendulum swing upon impact?

assuming the pendulum is straight down before the impact, its KE was 1/2 m 1^2
that KE is translated to PE as it swings.
mgh=1/2 m v^2
h= 1/(2g)
angle= arccos((.35-h)/.35)
