Question

If x= at + bt? where x is in m/s and t in s^-1, then find
out the units of 'a' and 'b' respectively.

​

Answer 1

Answer:

a - [L]

b - [L T]

Explanation:

[X] = [at]

=> [a] = [X] / [t] = [ L T^-1] / [T^-1] = [L]

similarly,

[X] = [b t^2]

=> [b] = [X] / [ t^2] = [ L T^-1] / [T^-2] = [L T]
