<span>The weight lifted by a machine to the applied force on a machine is called mechanical advantage.
This is written as Mechanical advantage, M. A, = load(weight)/effort.
So for 1) M.A = 2 and load = 2, 000lb = 8896.446N.
So 2 = 8896.446/ effort
Effort = 8896.446/2 = 4448.48
Similarly for M.A of 2, 000, 000 we have
Effort = 8896.446/ 2, 000, 000 = 0.004448</span>
Well the block will still have to deal with gravitational force. So here’s my prediction: Although the block is being dropped at different heights it will accelerate at the same speed no matter what and this is due to the earths gravitational energy (9.8m/s^2 or roughly 10m/s^2) so the only thing that will change is the height that the object is dropped.
Power = energy / time
Multiply each side by 'time', then
divide each side by 'power':
Time = energy / power
Time = 432 / 75 = <em>5.76 seconds</em>
1. that's 2 joules 1*2 = 2 j
2.that will be 20*3.5 = 70 j
3.that will be = 500*2.2= 1100 j
