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.
Sky divers do not go up, but they do undergo deceleration due to the increased drag incurred by the parachute being suddenly opened. Since skydivers, when being filmed by a cameraman, release their parachute first, there is a relative acceleration between the cameraman and the skydiver, creating the illusion that the skydiver is travelling up.
the crate will reach terminal velocity last, but hit the ground frist.
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
66.7 m/s2
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!

80 m/s2 up
Skydivers land safetly so that they do not get hurt! Did you mean something else?

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.
zero
The spreading of the arms and legs slows the fall and gives the skydiver more control of the fall.

If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
