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.
Initially, like any falling object, a skydiver's downward acceleration is 9.8 meters/seconds^2, or about 28-35 feet per second squared. This acceleration reduces over a few seconds and approaches zero as the skydiver reaches terminal velocity. This is because air resistance becomes a larger and larger force as speed increases.
Initially, the skydiver will experience an acceleration due to gravity, which is approximately 9.81 m/s^2 downward. As the skydiver falls, air resistance will oppose this acceleration, causing the skydiver to reach a terminal velocity where the downward acceleration due to gravity is balanced by the upward force of air resistance.
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.
When a skydiver reaches terminal speed, the air resistance is equal to the force of gravity acting on the skydiver. At this point, the acceleration of the skydiver is zero, as the forces are balanced. This means that the skydiver is falling at a constant speed due to the opposing forces being equal.
When a skydiver jumps out of a hovering helicopter with forward velocity, the skydiver's initial velocity will be a combination of the helicopter's forward velocity and the vertical velocity due to gravity. As the skydiver falls, their acceleration is primarily due to gravity acting downward, with air resistance also playing a role. The acceleration experienced by the skydiver will be constant at approximately 9.8 m/s^2 downward, ignoring air resistance.
Yes, if the acceleration of the skydiver decreases as falling progresses, it means the skydiver is slowing down. This indicates that the force of gravity pulling the skydiver downward is being countered by air resistance, causing the skydiver to decelerate.
zero
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
If the 0.75 refers to seconds, then his acceleration is -66.66... (repeating) metres per second^2.
A skydiver's velocity after 2 seconds will depend on factors such as their initial velocity, weight, air resistance, and gravitational force acting on them. On average, a skydiver will reach a terminal velocity of around 120 mph (193 km/h) after about 10 seconds of freefall.
When a skydiver is accelerating downward, the forces are unbalanced. The force of gravity acting downward on the skydiver is greater than the air resistance force pushing upward, causing the skydiver to accelerate downward.
80 m/s 2 up
The skydiver's acceleration will be due to gravity, causing them to accelerate downwards at a rate of 9.8 m/s^2 (assuming no air resistance).
