an ideal machine
At perfect 100% efficiency, the Actual Mechanical Advantage should equal the Ideal Mechanical Advantage.
When a machine is 100% efficient, theoretical and actual MAs are the same. Please let me know when you run across one of these.
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
yes
100%. There are no accidents with motor vehicles. There are only failures to avoid collisions.

I am uncertain if that particular statistic is accurate, but the vast majority of collisions ARE caused by driver inattention or error.

mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
