A body falls from rest under gravity, the velocity “v” is given by v=kgp h q , where h is the distance fallen through, g the acc
eleration of gravity, and k, p and q are constants. Which relation is the one that satisfies the dimensional analysis:
1 answer:
The relation that satisfies the the dimensional analysis is ![1[LT^{-1} ]= k[L^{p+q} T^{-2p}]](https://tex.z-dn.net/?f=1%5BLT%5E%7B-1%7D%20%5D%3D%20k%5BL%5E%7Bp%2Bq%7D%20T%5E%7B-2p%7D%5D)
<em>Your velocity equation seems to be incorrectly typed, below is the equation is I presume you intended to type;</em>

The dimensional analysis of the velocity equation is calculated as follows;

where;
k, p and q are constant
h is the distance (m)
g is acceleration due to gravity (m/s²)
v is the velocity (m/s)
![v = kg^ph^q\\\\LT^{-1} = k[LT^{-2}]^p[L]^q\\\\LT^{-1} = k[L^pT^{-2p}][L^q]\\\\1[LT^{-1} ]= k[L^{p+q} T^{-2p}]\\\\1 = k\\\\L^1 = L^{p+q} \\\\1 = p+q\\\\T^{-1} = T^{-2p}\\\\](https://tex.z-dn.net/?f=v%20%3D%20kg%5Eph%5Eq%5C%5C%5C%5CLT%5E%7B-1%7D%20%3D%20k%5BLT%5E%7B-2%7D%5D%5Ep%5BL%5D%5Eq%5C%5C%5C%5CLT%5E%7B-1%7D%20%3D%20k%5BL%5EpT%5E%7B-2p%7D%5D%5BL%5Eq%5D%5C%5C%5C%5C1%5BLT%5E%7B-1%7D%20%5D%3D%20k%5BL%5E%7Bp%2Bq%7D%20T%5E%7B-2p%7D%5D%5C%5C%5C%5C1%20%3D%20k%5C%5C%5C%5CL%5E1%20%3D%20L%5E%7Bp%2Bq%7D%20%5C%5C%5C%5C1%20%3D%20p%2Bq%5C%5C%5C%5CT%5E%7B-1%7D%20%20%3D%20T%5E%7B-2p%7D%5C%5C%5C%5C)
Thus, the relation that satisfies the the dimensional analysis is ![1[LT^{-1} ]= k[L^{p+q} T^{-2p}]](https://tex.z-dn.net/?f=1%5BLT%5E%7B-1%7D%20%5D%3D%20k%5BL%5E%7Bp%2Bq%7D%20T%5E%7B-2p%7D%5D)
