The speed, v, of an object is given by the equation v=At^3-Bt, where t refers to time. What are the dimension of A and B?

Respuesta :

AL2006
[v] = [speed] = [length/time]

[A] · [time³]  =  [length/time]

[A]                = [ length/time⁴ ]
_____________________________

[v] = [speed] = [length/time]

[B] · [time]  =  [length/time]

[B]                = [ length/time² ] = acceleration
