I'm thinking 1 is out because the base is wide and the force will dig in the front edge.
Two will get moving easiest, but the gravel is messing with my mind.
Three just needs to get moving and then its easy.
BUT will the pusher have the necessary grip on the ice to get it moving or will the gravel be the ultimate secret to success.
Damit, I don't know😀
Well, it's not the top one. Part of your force will be wasted by your hand trying to slide upward, so you'll have to waste force pushing down as well as forward. The other issue with ice is that you're gonna be sliding backward as you're pushing.
I'm going with the one on gravel, unless the pusher has microspikes while on ice.
When one is taking the question literaly, it would be eighter one of the two ice. Nowhere in the question there is a requirement for the object to move. It is questioned for the least force. So one could say, when the person slides on the ice, the force on the object should be smaller then the force on the round object on gravel.
Ha, I never even considered that the object didnt need to move. Makes sense
it's one because triangles are easier to push
Assuming that the ground is ice.......... The sphere.
