1. Homework Statement



A baseball is hit at ground level. The ball reaches its maximum height above ground level 3.1 s after being hit. Then 2.6 s after reaching its maximum height, the ball barely clears a fence that is 97.2 m from where it was hit. Assume the ground is level.

a) How far beyond the fence does the ball strike the ground?

V = x/t

Welcome to the physics forums,

You should show your attempt at a solution (or at least explain your thought process, and where you're stuck at) so that you can be helped where you need it

How high is the fence? That would seem to be an essential piece of information.

You shouldn't need to know that to solve the problem

I agree with Nathanael . The height of the fence is not required .

Ditto. The problem is easier than it looks at first glance.

this seems like more of a math question than a physics one. A hint is that the ball follows the path of a trajectory meaning that the path it takes to rise to its maximum point is symmetrical to its fall back to the ground.

Indeed. All that is needed for the OP's problem (which I note is designated as part (a)) is that the ball clears the fence. Adding "barely" suggests that part (b) of the problem is "approximately how tall is the fence?"

Probably best to let the OP have a go at it now.
