Question
Imagine that you're loading a pickup truck with bags of groceries. You notice that the smaller the weight you attempt to lift, the quicker you can lift it. However, you also notice that there is a limit to how quickly you can lift even very small weights, and that above a certain weight, you can no longer lift the weight at all. The detailed relationship between the contraction velocity of a muscle (the speed with which you can lift something) and the weight you are attempting to lift, is known as Hill's law. Based on this description, which of the following graphs of velocity vs force it a possible representation of Hill's law? (Figure 1)Explanation / Answer
According to the description,
1. As the lifting force increases the velocity decreases
2. There is a limit for maximum speed, with with the lighest object can be lifted
3. At a certain but not infinite force we can no longer be able to lift the weight which means velocity =0
so among all the curves, Curve E fits correctly as is is meeting the the above three conditions
velocity is decreasing as foce is increased
there is a highest speed for lowest force
velocity became zero at a certain finite force
