850
To find the value of F drag, we need to know the formula for drag force. In this case, we can use the formula for drag force: F drag = 0.5 * ρ * A * Cd * v^2, where ρ is the air density, A is the cross-sectional area of the parachute, Cd is the drag coefficient, and v is the velocity.
However, we don't have all the necessary values to directly calculate F drag in this situation. We would need to know the air density, cross-sectional area of the parachute, drag coefficient, and the velocity at which the parachute is falling.
Moving on to the net force, it is the vector sum of all the forces acting on an object. In this case, we have two forces: the gravitational force (Fg = 850N) acting downwards and the drag force (F drag) acting upwards. The net force is the difference between these two forces: Net force = F drag - Fg.
As for acceleration, we can use the formula F = ma, where F is the net force and a is the acceleration. Rearranging the formula, we have a = F/net. So, we can calculate the acceleration by dividing the net force by the mass of the parachute. However, we don't have the mass of the parachute, so we can't determine the exact value of the acceleration.
Regarding the question about whether the forces are balanced or unbalanced, we can analyze their directions. The gravitational force (Fg) and drag force (F drag) act in opposite directions, suggesting that they are unbalanced forces. The parachute will experience a net upward force due to drag, causing it to slow down and ultimately reach terminal velocity.
