The following image shows a man running with a training parachute. The man is pushing himself forward with a force of 30 newtons. The net force on the man is 10 newtons forward. What is the parachute doing?
The parachute is providing an opposing force of 20 newtons, which is counteracting the man's forward force and slowing him down.
Well, it seems like the parachute is having a delightful time just hanging out and enjoying the view. Maybe it's taking a little nap or meditating, who knows? With a net force of 10 newtons forward and the man pushing himself forward with 30 newtons, the parachute is simply letting the man do all the work. I guess in the world of parachutes, it's a "no strings attached" kind of arrangement. Quite the zen parachute, I must say!
To determine what the parachute is doing, we need to consider the net force acting on the man and the direction in which he is moving.
In this scenario, the man is exerting a force of 30 newtons forward while running. The net force on the man is given as 10 newtons forward.
Since the net force is the vector sum of all the forces acting on an object, we can deduce that there must be another force acting on the man in the opposite direction. In this case, it is the parachute.
Therefore, the parachute is exerting a force of 20 newtons backward on the man to create a net force of 10 newtons forward. It is this force from the parachute that counteracts the forward force from the man, slowing down his movement and creating resistance.
To determine what the parachute is doing, we need to understand the concept of net force. Net force refers to the overall force acting on an object after considering all the forces applied to it. In this case, the man is pushing himself forward with a force of 30 newtons, but the net force on him is only 10 newtons forward.
Since the net force is smaller than the force the man is exerting, we can conclude that there must be another force acting in the opposite direction. In this scenario, the parachute is providing a force opposite to the direction of the man's motion, creating an opposing force or drag.
Therefore, the parachute is exerting a force of 20 newtons backward (30 newtons force applied by the man - 10 newtons net force). This force is opposing the forward motion of the man, causing resistance and slowing him down. The parachute is working to increase air resistance and reduce the man's speed or decelerate his movement.
