Answer:
The net force is 392N, pointing down.
Explanation:
The net force is the sum of all forces acting on the rock, namely the gravity ("+" acting downward) and the friction force due to air resistance ("-" acting upward):
The net force is 392N and pointing down (positive)/
The second option is the correct one. m/s^2
gas, liquid, and solid
The correct solution is "14.6875 kg".
Given values:
