To find the speed of the object, we can use the formula for kinetic energy:
where
is the kinetic energy,
is the mass, and
is the velocity.Given:-
J-
kgWe need to solve for
:
First, multiply both sides by 2 to get rid of the fraction:
Next, divide both sides by 34:
Finally, take the square root of both sides to solve for
:
So, the object is moving at approximately 1.21 m/s.
