Gavin is kicking one of his toy cars with a force straight ahead. the car weighs 1.2 kg and has friction free wheels so that the friction forces of the car is small when it has started. Gavin kicks his car with the force of 2.4 N. How large is the resultant force?
The Attempt at a Solution
If there is no friction then the resultant force should be pointing forward but my book is saying that the resultant force is zero. why?
