Question
What is the net force acting on a car cruising at a constant velocity of $70 \mathrm{km} / \mathrm{h}(a)$ on a level road and $(b)$ on an uphill road?
Step 1
The net force acting on an object is the vector sum of all the forces acting on it. If an object is moving with a constant velocity, it means there is no acceleration. According to Newton's second law, Force equals mass times acceleration (F=ma). Show more…
