Question

A force f is given by f = at +bt^2, where t is time the dimensions of a and b are

Answer 1

Explanation:

this will be the answer

Answer 2

F = ax + bt^2

$f = ax \\ \\ a = \frac{f}{x} = \frac{ {m}^{1} {l}^{1} {t}^{ - 2} }{ {l}^{1} } \\ \\ a = {m}^{1} {t}^{ - 2} \\ \\ f = b {t}^{2} \\ \\ b = \frac{f}{ {t}^{2} } = \frac{ {m}^{1} {l}^{1} {t}^{ - 2} }{ {t}^{2} } = {m}^{ 1} {l}^{1} {t}^{ - 2} {t}^{ - 2} \\ \\ b = {m}^{ 1} {l}^{1} {t}^{ - 4}$
