# A remote control car has a mass of #15.5kg# and is accelerating on the road. The car starts from rest and reaches a velocity of #11m/s[E]# in #19.5s#. What is the force applied by the car on the road? Neglect frictional forces.

F = ma, but in this case, a = gravity

#### Explanation:

The force the car applies to the road is independent of how fast it is going. This is a distractor question to see if you understand that difference. So, your answer is simply

Note that if the roadway is pitched to an angle, that downward force will change, but it is still independent of the speed the car is traveling.
