3m/sec*2m/sec= 6 m^2/sec^2 ???

Is this right??

Yes

Yes, that is correct. When multiplying two quantities with units, such as 3 m/sec and 2 m/sec, you also multiply the units. In this case, you are multiplying meters per second by meters per second, resulting in square meters per square second, or m^2/sec^2. Therefore, 3 m/sec * 2 m/sec = 6 m^2/sec^2.
