300J of work are required to fully drive a stake into the ground If the average resistive force on the stake by the ground is 716 N how long is the stake?

In physics, Work = Force x Distance (W=Fd)
We know that:
W = 300 J
F = 716 N
We dont know:
d = ?
The equation we will use is W = Fd
Substituting in for what we know:
300 J = (716 N) x d
Rearranging for d:
d = (300 J)/(716 N)
Solving for d:
d = 0.419 m
What this tells us is that the distance the stake was pounded into the ground is 0.419 meters. We cannot determine the length of the stake without knowing more information.

How many hp is required to drive an alternator?
The more load that is put on the alternator the more power is required to drive it. This is an interesting question and I really do not have the exact number. But I do know from spinning an alternator with my hand that is takes very little power to turn it when it is not connected to anything. But connect it to a battery that is dead and it takes some power to spin it. I would estimate it takes from 2-3 hp depending on the load. #2 Approximately 1 HP is required to drive an alternator for every 746 watts of electrical power it produces. In practice 1 HP of mechanical power produces a little less than 746 watts at the output because of frictional and resistive losses.
