In

\mathrm{\;S} = a + bt + c{t^2}

. S is measured in metre and t in second. The unit of c is

View answer and explanation

Correct option: D

m{s^{ - 2}}

Option D (

m{s^{ - 2}}

) is correct because in the equation

S = a + bt + ct^2

, each term must have the same dimensions as S (which is in meters). Therefore,

ct^2

must have dimensions of meters, implying c has units of

m/s^2

.
