When a parachutist is moving with a constant speed what happens?
There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity. The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!
How do you calculate geometric probability?
In the simplest case, a geometric probability is one that is given in terms of the ratio of two areas. For example, suppose a parachutist could land anywhere on a 10 square kilometre area of open country with equal probability, and you wanted to know how probable it would be that the parachutist would land on a designated area of 2 square kilometres with that part of open country. Then the probability would be 2 / 10 = 0.2 The same principles apply in more and more difficult or complex cases, and in spaces of higher dimension. For instance, one can discuss geometric probabilities involving three-dimensional space.
What is some examples of gravitational potential energy?
Any object that is higher than ground level in earth's gravitational field has potential energy stored in it. Examples: 1. A plane or bird in the sky 2. A parachutist 3. Water stored in a dam, or water tanks at some height above earth's surface 4. A satellite orbiting Earth
What is maximum velocity?
maximum velocity is the highest possibly speed an object can travel before the forces acting on it reach an equilibrium and it is no longer able to accelerate. For example a parachutist will fall and accelerate rapidly until the air resistance pushing upwards against her downward force becomes balanced and her speed is steady, its more commonly known as 'terminal velocity' not maximum.
