Nonzero velocity at top of trajectory
I found a conceptual problem that I thought should be easy but I am having a difficult time with.
"How can you throw a projectile so that it has zero speed at the top of its trajectory? So that it has nonzero speed at the top of its trajectory?"
Isn't velocity always zero at the top point of a trajectory?

I'm going to assume you are referring the speed in the y-direction. If that is the case, then yes there will always be a zero at the top point of a trajectory, especially in simple cases such as in our regular everyday gravitational experiences.
