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, the slowing of a skydiver after the parachute opens is an example of inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the parachute deploys, it creates drag that opposes the skydiver's downward motion, causing a rapid deceleration. The skydiver’s mass and the initial downward momentum illustrate inertia, as the parachute must exert a force to overcome this momentum.
35,000ft (A380-800, initial cruise altitude). The service ceiling (maximum altitude) of this aircraft is 43,000 ft.
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.
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.
66.7 m/s2
66.7 m/s2
Assuming the skydiver starts at rest and accelerates at a rate of 9.8 m/s^2 due to gravity, the velocity after one second would be 9.8 m/s downward. This is because velocity is the initial velocity of 0 m/s plus the acceleration of 9.8 m/s^2 multiplied by 1 second.
An object dropped from a height without any initial velocity, a skydiver falling towards the ground before deploying their parachute, and a rock falling off a cliff are all examples of free fall.
As the launch angle of a projectile increases from 30 to 45 degrees, the maximum altitude generally increases. This is because a higher launch angle allows for a greater vertical component of the initial velocity, which contributes to a higher peak in the projectile's trajectory. However, beyond 45 degrees, the altitude will begin to decrease as the horizontal component of the velocity becomes less efficient for achieving height. Thus, the maximum altitude reaches its peak at or around 45 degrees for a given initial velocity.
No, the object would continue to fall towards the Earth due to the force of gravity, even if the helicopter is rising. The object's initial upward velocity from the helicopter's motion would not be enough to counteract the force of gravity pulling it down.
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.
