What else can I help you with?
What is a change in velocity in given period of time?
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
What is initial velocity?
Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
What are units for velocity squared?
The SI unit for velocity is m/s. Therefore the SI units for velocity squared would be m2/s2.
What is the formula for speed or velocity?
velocity=distance/time -or- v=d/t
A skydiver jumps out of a hovering helicopter so there is a fou out of a hovering helicopter so there is no forward velocity. what is the skydivers acceleration?
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).
What happens when a Skydiver Jumps Out Of A Hovering Helicopter So There Is Forward Velocity. What Is The Skydiver's Acceleration?
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.
What is the terminal velocity of skydivers?
187 miles per hour.
Why do skydivers reach terminal 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.
Do all skydivers fall at the same speed?
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.
When a skydiver jumps out of a hovering helicopter so there is forward velocity. what is the skydiver's acceleration?
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.
Does a skydivers decreases her acceleration when falling 5 seconds before reaching her terminal velocity?
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.
When the skydiver steps out of the helicopter someone who's watching starts a stopwatch. So the time is zero as the skydiver steps out of the plane. What is the skydiver's downward velocity at that?
At the moment the skydiver exits the helicopter, their downward velocity is initially zero. As they fall due to gravity, their velocity will increase over time.
What is the velocity of a cargo helicopter?
Different models of helicopter have different performance stats. Impossible to answer without knowing which one you had in mind.
What is the skydivers forward velocity after 1 second?
The skydiver's forward velocity after 1 second would depend on factors such as their body position, weight, and air resistance. On average, a skydiver in freefall might reach a forward velocity of around 120 mph (193 km/h) after 1 second.
Does rain reach terminal velocity?
No, raindrops do not reach terminal velocity because they are too small and have a low enough mass that air resistance slows them down before they can reach their maximum falling speed. Terminal velocity is typically reached by larger objects like skydivers or hailstones.
What is effect of the weight of the helicopter on the terminal speed - slide3?
The weight of the helicopter affects the terminal speed by influencing the rate at which the helicopter falls. A heavier helicopter will reach a higher terminal velocity compared to a lighter helicopter, as the force of gravity will be greater on the heavier helicopter, causing it to accelerate faster. Additionally, a heavier helicopter may require more lift to counteract its weight, which can also impact its terminal speed.
