5850J=(1/2)(45kg)(v)^2
Find V!
Show steps please!

V=±2√65kgJ/kg

Explanation:

Rewrite the equation as (1/2)(45kg)(V^2)=5850J

(1/2)(45kg)(V^2)=5850J

Simplify

K*45g(v)^2/2=5850J

Multiply each term by 2/45kg and simplify.

v^2=260J/Kg

Take the square root of both sides of the equation to eliminate the exponent on the left side.

v=±√260J/kg

The complete solution is the result of both the positive and negative portions of the solution.

V=2√65kgJ/kg

V=-2√65kgJ/kg
