A cook holds a 2.00 kg carton of milk at arm's length. What force http://www.webassign.net/images/boldF.gifB must be exerted by the biceps muscle? (Ignore the weight of the forearm.)
I have been trying for a while to figure this one out and its just not coming to me. I know the answer is supposed to be 312N. Any help would be appreciated. Thanks.
