Question

PLEASE HELP THIS IS DUE LIKE HELP ME PLEASE

On the image at the right, select the point where the pendulum swings fastest. Then, select two points with a velocity is zero.

Answer 1

At the end points of motion (either side) the velocity must be zero because the velocity is changing from - to + (it can't turn around around without passing thru zero,

The velocity will then increase to the midpoint of the motion.

m g h = 1/2 m v^2 where h is the vertical distance thru which the pendulum travels
