btw ^ = squared by 2 does anyone know what this means in physics the formula W = 1/2 m (v^ - u^) what is m if w = 240 v = 6 and u = 4?

does anyone know what this means,
in physics the formula W = 1/2 m (v^ - u^)
what is m if w = 240 v = 6 and u = 4

Just so you know, "^" does not mean "squared by 2".
"^" means "the following number is the exponent."
Then "^2" means "squared" or "raised to the second power,"
E = mc^2
So your formula should read
W = ½m(v^2 - u^2)
which represents the fact that the work done on an object is equal to the change in its kinetic energy.
Assuming your values are in SI units, then,
240 = ½m*(6^2 - 4^2)
which solves to
m = 24 (kg)
