when a monkey is released with its legs up,it lands with its legs .who provides torque to it so that it rotates?

OpenStudy (jamesj):

By doing something like this cat: http://www.youtube.com/watch?feature=endscreen&NR=1&v=yGusK69XVlk

OpenStudy (ganpat):

The weight inside the monkey is distributed more in legs.. SO it tends to turn it upside down when he the monkey is freely falling.. Does that answers your question ?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

@JamesJ what does cat do??

OpenStudy (anonymous):

@JamesJ yes i got it

OpenStudy (ganpat):

The claw of the monkey is heavier than, its rest of the body.. So when it falls freely the leg tends to go first than his body.. For eg.. if u and ur friend fall freely from certain ht, and say some weight is added to ur friends body.. he will fall faster that you ...

OpenStudy (anonymous):

why legs go faster as acceleration will be g

OpenStudy (jamesj):

@ganpat, that is most definitely wrong as your explanation of the violation of basic Newtonian physics: the gravitational force near the surface of the earth on a mass \( m \) is \( mg \) which is by Newton's second law equal to \( ma \). Hence \[ mg = ma \] i.e., the acceleration \( a \) for every mass \( m \) is \[ a = g\]

OpenStudy (anonymous):

thats i want to say

OpenStudy (anonymous):

I would think that it uses its body to create drag in the air and thus spin?

OpenStudy (jamesj):

The monkey doesn't have enough time in fall in order to do this. It almost certainly contorts its body as the cat does.

OpenStudy (anonymous):

how it will creat drag and its value will be less so how it can rotate such a mass

OpenStudy (ganpat):

@JamesJ : well, m = a i agree.. but mass for different things can vary.. right ?

OpenStudy (jamesj):

a = g, not m = a.

OpenStudy (ganpat):

i understood that.. a = g = 9.81 m/s2.. But for u m= x N.. anf for me it y N.. How do u define that..
