Homework Help: Pendulum Maximum Height

  1. Oct 7, 2012 #1
    I have a physics lab tomorrow and have to answer this question to be admitted in. We haven't begun to talk about Pendulums in lecture yet, so I have NO idea where to start. Here's the question:
    A mass of 40 kg suspended from a 43-cm long light string forms a simple pendulum. The mass swings through the lowest point of its trajectory with a speed of 1.6 m/s. To what maximum height above the lowest point will it rise (in m)? Neglect air resistance.

    Could you PLEASE walk me through how to solve this? I've looked online but can't seem to find an equation for determining the maximum height. Thank you!

    Think about how pendulum energy oscillates between potential energy and kinetic energy.
