What are the chances we can take a look at our previous exam to see which problems exactly we got wrong?
I had planned to return your exam packets this morning at the lecture but that’ll have to wait until Wednesday morning now.
To find the magnitudes of each block (if we are expected to use F=ma), would the acceleration be equal to 0 because the block is not moving, or would it be equal to acceleration due to gravity, in this case?
In this case, the blocks are at rest initially and remain at rest. This means they have acceleration = 0, which in turns means that the net force acting on each of the blocks = 0.
I am having some trouble with the last Mastering physics problem in trying to figure out the magnitude of acceleration. If we are supposed to use F=ma, which mass do we use if they say to ignore the mass of the bear? Also do we have to find Fnet by using components? There seems to be something I am doing wrong.
thanks!
