Find the average force the cylinder exerts on the nail while pushing it into the block. Ignore the effects of the air. Express your answer with the appropriate units.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
