O The work done by the pulling force and friction are both positive O The work done by the pulling force is negative, while the work done by friction is positive O The work done by the pulling force and friction are both negative O The work done by the pulling force is positive, while the work done by friction is negative If an object's speed is increased 2 times, keeping it's mass the same, what happens to the amount of kinetic energy? O Increases by 2 times O Increases by 4 times O Decreases by 2 times O Remains the same An object with Kinetic Energy must be Moving At rest ) High above the earth () None of the above
