A 50 kg object is falling, with a 10 N air resistance acting on it. What is the net force acting on that object? Use acceleration due to gravity = 10 m/s
The net force acting on an object is the sum of all forces acting on it. In this case, the only forces acting on the object are gravity and air resistance.
The force of gravity acting on the object can be calculated using the formula:
Fg = m * g
Where:
Fg = force of gravity
m = mass of the object (50 kg)
g = acceleration due to gravity (10 m/s^2)
Fg = 50 kg * 10 m/s^2 = 500 N
The net force can be calculated by subtracting the force of air resistance from the force of gravity:
Net force = Fg - Fair
Net force = 500 N - 10 N = 490 N
Therefore, the net force acting on the object is 490 N.
