How many meters will a 2kg ball moves starting from rest fall freely in one second?
The mass is irrelevant. If the object is in free fall (that is, air resistance can be neglected), an object will fall 4.9 meters in one second.
What is the speed of an object in free fall 2 seconds after falling from rest?
Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
True or false a linear regression is useful for modeling the position of an object in free fall?
true, liner regression is useful for modeling the position of an object in free fall
What is the rate of change of free fall acceleration when an object is released into a free fall and can it be verified experimentally and how?
Take a position equation found experimentally, s(t), and take a double derivative. The first d/dx is velocity and the second is acceleration.
How far in meters does an object fall in 2 seconds?
if the object is falling straight then the force from which the ball is falling toward earth is the gravitational force of the earth that is 9.81 m/sec2. so by formula we have, speed=distance/time ,also distance=speed*time here if the ball is freely falling that is no external force is applied on ball then the s=gravitational pull and time given is 2 sec there for in 2 sec the object fall ; d=9.8 m/sec2 *2 sec d=18.36 m(approx) if any other suggestion then do tell me I am no expert but I do believe the correct formula to use for this situation is d=1/2 gt2. The formula above will only work for example if you are traveling at a constant velocity in a car of 9.8 meters per second. You need to take into account that an object in free fall is constantly accelerating and not in a constant motion. The correct answer should be closer to 19.6 m.
