Answer:
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
