Answer: To find the value of m in the equation W = 1/2 * m * v^2, you need to know the values of W and v. The variable m represents the mass of the object, and W represents the kinetic energy of the object. The equation states that the kinetic energy of an object is equal to 1/2 of its mass multiplied by its velocity squared.

If you are given the values of W and v, you can solve for m by rearranging the equation as follows:

m = 2 * W / v^2

Plugging in the values of W and v will give you the value of m.

For example, if W = 100 joules and v = 10 meters per second, the equation would be:

m = 2 * 100 joules / 10 m/s^2 = 20 kilograms

This is the mass of the object.

Answer:


m=(2W)/(v^(2) ).

Explanation:

1. Write the expression.


W=(1)/(2) mv^(2)

2. Divide both sides of the equation by
(1)/(2) and
v^(2).


(W)/((1)/(2) v^(2) )=m\\ \\

3. Rewrite and simplify.


m=(W)/((1)/(2) v^(2) )\\ \\m=(2W)/(v^(2) ).
