Not really a homework problem, but I wasn't sure where to post this. I'm looking at updating the horseshoe pits at work. Regulation courts suggest using concrete as a surround to the clay/sand pit. The question I have is: If I substitute concrete tiles with a sand substrate will it stand up to the impact force of a 42 oz horseshoe thrown from 40' away. The assumptions I think I need to make include: Max Height of throw 12 ft Total time of throw 2.5 sec. I think this should be a simple cannon ball type problem, but not sure how to proceed, having been out of physics for close to 15 years. Thanks for any help you can give.
