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.
The average velocity for the first 3 seconds of a skydiver's free fall would depend on the initial speed, air resistance, and gravitational acceleration, but generally, it could be around 55-60 m/s.
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
Skydivers reach terminal velocity because as they fall, the force of gravity pulling them downward is balanced by air resistance pushing upward. At terminal velocity, these forces are equal, so the skydiver stops accelerating and falls at a constant speed.
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.
No, skydivers fall at different speeds depending on their body position and weight. However, experienced skydivers often aim for a terminal velocity of around 120 mph (193 km/h) to maximize their control and safety during freefall.

187 miles per hour.
Skydivers reach terminal velocity because as they fall, the force of gravity pulling them downward is balanced by air resistance pushing upward. At terminal velocity, these forces are equal, so the skydiver stops accelerating and falls at a constant speed.
To calculate this, you divide the change in velocity, by the time.

Neglecting air resistance his velocity after 1 second will be 9.81 m/sec or 32.2 ft/sec.
Velocity increases after 5 seconds
He will decelerate (meaning an acceleration in the direction opposite of current velocity) at a rate of (54 m/s - 4 m/s)/.75 seconds = 66.67 m/s2. This is about 6.8 Gs.
Velocity is derived by dividing displacement with time in seconds
