When a skydiver jumps from an airplane the distance d in feet the diver falls in t seconds before opening the parachute is given by the formula Test Image. The formula assumes that there is no air res?
If d = 16*t^2 then there is no significant air resistance.
If an object falls with constant acceleration the velocity of the object must?
Changing at a constant rate equal to acceleration.
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
What is the formula in finding the frequency distribution?
The frequency distribution usually refers to empirical measurement and there is no formula for finding it. You simply count the number of times an observation falls within a given range.
How does velocity varies with the vertical distance traveled by the object?
When an object falls vertically downward, its velocity increases according to the following equation:2aS=vf2 - vi2 or ,2*10*S=v2, orv=(20S)1/2.There is a second case in which a body is thrown vertically upward, here its velocity decreases as it moves upward. Here its velocity becomes zero as it reaches the highest point
How do you calculate the horizontal distance traveled by an object if you are given the horizontal velocity and time in the air?
You cannot because you do not know how long before the object falls to the ground and so stops moving.
The amount of gravitational potential energy released as an object falls depends on?
the height from which it falls and the mass of the object. The formula for gravitational potential energy is GPE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height from which the object falls.
An object weighing 75 N is dropped from the top of a building and falls a distance of 28 m tot he ground how much work does gravity do on the object from the time it is dropped to the time it hits th?
The work done by gravity on the object can be calculated using the formula: work = force × distance. In this case, the force of gravity on the object is its weight, which is 75 N. The distance it falls is 28 m. Therefore, the work done by gravity on the object is 75 N × 28 m = 2100 J.
How is the kinetic energy of an object determind?
If you know the velocity and the mass, you can use the formula: KE = (1/2) x mass x velocity2. Otherwise, you have do deduce it from other facts. For example, if an object of a certain mass falls from a certain height, you can calculate that it started with a certain amount of potential energy, and assume that after it falls, all of the energy has been converted to kinetic energy.If you know the velocity and the mass, you can use the formula: KE = (1/2) x mass x velocity2.

If an object falls twice as far how do you think the energy acquired changes?
If an object falls twice as far, it acquires twice as much potential energy due to the increase in height. The increase in potential energy is directly proportional to the distance the object falls.
What is the appropriate equation for how fast an object freely falls from a position of rest for how far that object falls?
The equation for the distance fallen by an object freely falling from rest can be calculated using the formula d = (1/2) * g * t^2, where d is the distance fallen, g is the acceleration due to gravity (approx. 9.81 m/s^2), and t is the time elapsed.
An object is dropped and is in free fall The speed of the falling object and the distance it falls are measured every second Which of the following is correct?
The speed stays thesame but the distance stays the same.
What formula do you use to determine how far an object falls?
ehmm... I'm not sure... what do you want to throw?
What Is the appropiate aquation for how fast an object freely falls from a position of rest For how far that object falls?
for how fast an object falls, use v=gt. g stands for the acceleration of gravity- 9.8 m/s2 v stands for speed t stands for time for how far that object falls, use d=0.5gt2 d being distance
How is potential energy transforme into kintetic energy?
When an object falls down.When an object falls down.When an object falls down.When an object falls down.
The distance that a free falling object falls is directly proportional to the square of the time it falls (before it hits the ground). If an object fell 91 ft in 2 seconds how far will it have fallen?
The answer is 91 ft, of course!
Formula for speed of an object?
If an object is at rest then falls vertically you can use the formula Vsquared=Usquared+2AD (Sorry keyboard wont let me do the 2 for square)Where V = Final Velocity (speed),U=Initial velocity (at rest =0)A= Acceleration (9.81 metres/sec or 32ft/sec in imperial)S= Distance.An object on a shelf 3m above the ground falls. Speed on impact with the floor would beSquare root V= 0 squared+2*9.81*3: = 7.672m/sSpeed = Distance/Time (Distance divided by Time)Speed=distance/timeSpeed is measured in m/s (meters per second)You can calculate speed using the following formula :Speed = Distance/TimeExamples:distance=100 meters=20s s=d/ts=100m/20ss= 5m/sthe units for speed equal up to m/s units always.so then your speed is 5 m/s
