Question

If the distance d (in meters) traveled by an object in time t (in seconds) is given by the formula d=a+bt2, the si units of a and b must be

Answer 1

Distance , d = a+b$t^2$

The unit of d is in meter and t is in seconds.

So the unit of a a must be meter.

Now we have unit of b$t^2$ is meter.

So unit of b*$second^2$ = meter

Unit of b = meter/$second^2$

So unit of a = m and unit of b = m/$s^2$.
