# Thread: Dynamics Problem

1. ## Dynamics Problem

I have a plate being driven on rollers at a constant velocity. The plate then hits a block and stops the plate. I am trying to find with what force the plate hits the block. Any ideas?

2. bjfroese,

F=MA
M=mass of the plate
A=Acceleration

What is the block made of, does it have a spring behind it to cushion the shock?
How fast is the plate traveling?
I have not checked this site but I would immagine there are equations for determining the acceleration or in this case dceleration of the plate.
If the block is solid with no "give", then things get a litttle more complex as you need to calculate impulse or "shock" loading and the forces can get high fast.
Hope this points you in the right direction.

Regards,

3. How much effort did you make to find an answer.

I "googled" "forces of impact" and got 156,000,000 results.

Why can't you?

If you make an effort and have a problem understanding the answer I would gladly help you.
