Question: If at the lowest point of its arc Mass M has a velocity of ten meters per second, then at how many points in time during the period of one complete cycle does the pendulum have a speed of five meters per second?
The answer is 4 times
And the explanation says it goes back and forth (once each time) = 2 total times, and there are two points where there are 5 m/s ....but I don't understand how there are two points where it's 5 m/s?
