Question 1 of 19
1. Question
A mass is attached to a spring, which is fixed to a wall. The mass is pulled away from the spring’s equilibrium point and is then released. At what point does the mass experience its maximum kinetic energy?
CorrectIncorrect 
Question 2 of 19
2. Question
A simple pendulum of length l swings at a radius r from a fixed point on the ceiling. As it moves, the pendulum creates an angle θ with the line that extends vertically downwards from the fixed point. At what angle does the mass attached to the pendulum have the highest kinetic energy?
CorrectIncorrect
