When skydiver slows down from 54 meters to 4 meters by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
How long does it take on average for a human body accelerate to 78 mph in freefall?
Convert 78 mph to meters per second: 78 mph=35 meters/second The acceleration of earths gravity is 9.8 meters per second squared. This is constant. Therefore, using basic calculus, the velocity of a falling object is equal to 9.8 meters per second times the time it has fallen. 9.8*T=35 T=3.6 Thus, it takes roughly three and a half seconds for the average human body to accelerate to 78 miles per hour (assuming wind drag is inconsequential).
How fast is something falling in two seconds?
An object in free fall accelerates due to gravity at approximately 9.81 meters per second squared. After two seconds, its velocity can be calculated using the formula ( v = g \cdot t ), where ( g ) is the acceleration due to gravity. Thus, after two seconds, the object would be falling at about ( 19.62 ) meters per second (m/s) downward.
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.

How do you calculate the speed of AA free falling object?
That depends what data you are given. Close to the Earth's surface, such an object will accelerate at 9.8 meters/second2, so if it starts from rest, after "n" seconds, it will have a speed of "9.8n" meters/second.
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 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. For more questions about skydiving, see the attached link.
Gravity causes all falling objects to accelerate at a rate of 98 meters per seconds?
The acceleration due to gravity is 9.8 meters per second squared, not 98. This means that an object in free fall will increase its speed by 9.8 m/s every second.
What is the height of a tower if a rock dropped from it hits the ground after falling for 2 seconds?
19.6 meters / 64.4 ft
How far will a freely falling object fall from rest in 4 seconds?
Assuming the object is falling under gravity, it will fall approximately 78.4 meters in 4 seconds. This is based on the formula: distance = 0.5 x acceleration due to gravity x time squared.
How long does it take on average for a human body accelerate to 78 mph in freefall?
Convert 78 mph to meters per second: 78 mph=35 meters/second The acceleration of earths gravity is 9.8 meters per second squared. This is constant. Therefore, using basic calculus, the velocity of a falling object is equal to 9.8 meters per second times the time it has fallen. 9.8*T=35 T=3.6 Thus, it takes roughly three and a half seconds for the average human body to accelerate to 78 miles per hour (assuming wind drag is inconsequential).
An apple falls from a tree What is its velocity after 1.6 seconds?
The acceleration of gravity is 9.8 meters per second2 downward. 1.6 seconds after falling from a branch near the surface of the Earth, the apple's speed is 15.68 meters per second. It's velocity is 15.68 meters per second downward. The tree has to be really tall, since the apple falls 12.544 meters (about 41 feet) in 1.6 seconds.
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.
Ignoring the effects of air resistance what is the speed in of the object after falling 3 seconds?
Assuming (1) the object starts from rest, (2) air resistance is insignificant, the object speeds up by about 9.8 meters/second every second. That's the strength of the gravitational field. Just multiply this acceleration (9.8 meters/second2) by the time.
A skydiver slows down from 65 m s to 5 m s by opening the parachute If this takes 0.75 seconds what is the skydiver's acceleration?
The general formula for acceleration is [(final velocity) - (initial velocity)]/(time required for the change). In this instance, (5 - 65)/0.75 = -80 meters per second per second.
