A bag is gently pushed off the top of a wall at A and swings in a vertical plane at the end of a rope of length l. Determine the
angle θ for which the rope will break, knowing that it can withstand a maximum tension equal to twice the weight of the bag.

The formula for kinetic energy is 
. Thus, the equation for velocity is 
.
The kinetic energy of a moving object is given by
where m is the object's mass and v its velocity.
In our problem, the initial kinetic energy is:
while the final kinetic energy is:
So, the kinetic energy lost by Lucy and her bike is
