Question

A toy car is given a quick push so that it moves up an inclined ramp. After it is released, it moves up, reaches its highest point and moves back down again. Friction is so small it can be ignored. What net force acts on the car? 1. Net decreasing force down the ramp 2. Net increasing force up the ramp 3. Net force of zero 4. Net increasing force down the ramp 5. Net decreasing force up the ramp 6. Net constant force down the ramp 7. Net constant force up the ramp

Answer 1

6. constant force down

Step-by-step explanation:

drawing a free body diagram, and applying Newton's second law:

`\sum F=m.a\\\sum F=m*g*sin(\theta)`

as you can see the only force playing a role on the box is the force done by the weight. all the values remain constant and so the force.

the correct answer is 6
