Question

If you square the speed expressed in meters per second, in what unit will the answer be expressed?

Answer 1

m²/s²

There is no unit for that construct, other than in equations of motion. For example:

KE = ½mv²

v² = u² + 2ax

where:

v = final velocity

u = initial velocity

a = acceleration

x = distance

Answer 2

For example

Units of kinetic energy are mass·speed^2  

KE=0.5 x mass kg  x speed (m/s)^2

unit=kg-m^2/s^2

so v^2 has "unit" m^2/s^2

Answer 3

(meter/sec)^2 = meter^2/sec^2,whenever you multiply 2 numbers,you

multiply their units automatically.

Answer 4

m^2/sec
