Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the toy truck in the problem, we have
m = 0.1 kg is its mass
v = 1.1 m/s is its speed
Putting the numbers into the equation, we find
Both of them are substances which comes between the path of electricity but the difference is that one let the electricity to pass that is conductor and other acts as breaker in the connection which is a insulator.
