Distance , d = a+b
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 is meter.
So unit of b*
= meter
Unit of b = meter/
So unit of a = m and unit of b = m/
.
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
So unit of b*
Unit of b = meter/
So unit of a = m and unit of b = m/
