A skydiver of mass 100 kg experiences air resistance while falling How fast is the skydiver being accelerated at?
The acceleration of the skydiver can be calculated using Newton's second law: F = ma, where F is the force of gravity - air resistance, m is the mass of the skydiver, and a is the acceleration. The acceleration will depend on the exact value of air resistance acting on the skydiver.
What is the maximum speed of any one free falling object?
The maximum speed of a free falling object depends on factors such as the object's mass, surface area, and the gravitational force acting on it. In a vacuum, objects will free fall at the same rate regardless of mass, reaching a maximum speed known as terminal velocity, which is around 120 mph for a skydiver in Earth's atmosphere.
How does an open parachute increase the air resistance of a falling skydiver?
An open parachute increases air resistance by creating a large surface area that catches and slows down the air around it. This creates drag that counteracts the force of gravity, slowing the skydiver's descent. The inflated canopy also increases the overall mass of the skydiver-parachute system, further enhancing the air resistance.
Free falling object?
Any free falling object accelerates at towards the earth at 10 meters per second squared regardless of volume and mass. This is due to gravity.
If a skydiver with a mass of 70 kg accelerates to Earth at a rate of 9.8 ms2 due to gravity what is the force on the skydiver?
The force on the skydiver is equal to the mass of the skydiver multiplied by the acceleration due to gravity. In this case, the force would be 70 kg * 9.8 m/s^2 which equals 686 N.
Does changing the mass of a free falling body affect the value of the acceleration of gravity?
No, changing the mass of a free-falling body does not affect the value of the acceleration due to gravity. The acceleration due to gravity is a constant value that is independent of the mass of the object. All objects fall at the same rate in a vacuum due to gravity.
A skydiver with a mass of 60 kg jumps out of an airplane at a height 5000 m The acceleration due to gravity is 9.8m s2 What is the gravitational potential energy of the skydiver?
The gravitational potential energy of the skydiver can be calculated using the formula: GPE = mass * gravity * height. Plugging in the values, GPE = 60 kg * 9.8 m/s2 * 5000 m = 2,940,000 J. So, the gravitational potential energy of the skydiver is 2,940,000 Joules.
What would the force of a skydiver with a mass of 70 kg and accelerates at 9.8 ms2 be?
The force is 686 newtons. (Force = mass x acceleration).
Is the slowing of a skydiver after the parachute opens an example of inertia?
Yes, the slowing of a skydiver after the parachute opens is an example of inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the parachute deploys, it creates drag that opposes the skydiver's downward motion, causing a rapid deceleration. The skydiver’s mass and the initial downward momentum illustrate inertia, as the parachute must exert a force to overcome this momentum.
Terminal velosity of free falling mass in empty space is?
If the space is in outer space there can be no gas against which a terminal velocity can occur
What is the speed of a free falling object after ten seconds from rest?
The speed of a free falling object after ten seconds from rest is approximately 98 m/s. This speed is achieved due to the acceleration of gravity, which is about 9.8 m/s².
What is the skydiver acceleration?
Upon leaving the aircraft, a skydiver rapidly reaches something called terminal velocity. This is where the resistance of the air matches the mass of the skydiver. At this speed, the skydiver maintains a relatively constant speed. Typically this is around 120mph in a flat body position and takes approximately 10 seconds to reach.
