Assuming we neglect air resistance and start from rest in the vertical plane - use
v=u+at
so v = 0+(10x2) assuming g = 10N/kg
=20m/s
In practice it will be less because air resistance will tend to slow the skydiver down.

What is the skydivers velocity after two seconds?
We'll assume you mean 2 seconds AFTER he's jumped from the plane. A good estimate would be 9.8m/s times 2 (9.8m/s/s times 2 seconds -- the standard value of the acceleration due to gravity). In two seconds, the velocity would be low enough that air resistance could probably be ignored for purposes of answering your homework. So try 19.6 m/s, unless your teacher gave your data on the air resistance of the sky diver.
What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.
What is the skydivers average velocity for the 3 seconds?
14.715 m/s. This is worked out by knowing that gravity will accelerate a body at 9.81 (m/s)/s. The average velocity is the speed at 3s plus the speed at 0s divided by 2. Speed at 0s = 0 x 9.81 = 0 m/s Speed at 3s = 3 x 9.81 = 29.43 m/s (29.43 + 0) / 2 = 14.715 m/s.
If i move forward 5 meters in 2 seconds. what is my velocity?
5/2 = 2.5 m/s; velocity is distance divided by time

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.

With what initial velocity would an object have to be thrown downward to fall 240 meters in 5 seconds?
During the 5 seconds, gravity adds 5G = (5 x 9.78) = 48.9 meters/sec to the object's downward speed.During that time, it's average downward speed is 1/2 of [ Vi + (Vi + 48.9) ] = Vi + 24.45 m/s.In 5 seconds it falls 5(Vi + 24.45) = 5Vi + 122.25 meters.5Vi + 122.25 = 240 meters5Vi = 240 - 122.25 = 117.75 metersVi = 117.75 / 5 = 23.55 meters per sec.
When a ca passes 200 meter in 2 seconds What is the cars velocity?
100
The body travels 2mts in first 2 seconds and 2.2mts in next four seconds what will be the velocity at the seventh second?
heres the average 2.2 seconds
Lucille knocks her textbook off her desk After it has fallen for 2 seconds what is its velocity?
16.4
What is the velocity of a book after it has fallen for 2 seconds?
19.6 meters per second or about 44mph
Can bodies with different velocities have same acceleration?
Yes, velocity is acceleration x time. If acceleration is the same, velocity can be different as it changes with time. For example a car accelerating with constant acceleration will have a different velocity after 5 seconds than it will have at 2 seconds.
