My Parachute Sim Js v 5.3
Parachute Jump Simulator
- Select the mass of Jumper + parachute .
- Select the initial altitude AGL
- Select the speed of the plane.
- Select the wind speed and wind direction. Tip: Use the graph view tool to drag and adjust the x and y axes.
Q1 Sim :
Q1: The effect of Air Resistance:
1- Click on [New Sim] and select an initial altitude( Height above ground level) and mass (Typical mass of a parachute is 14 kg), then click [Finish]. 2- Start the simulation and allow the jumper to fall freely WITHOUT deploying the parachute. Note the vertical velocity of the jumper when he hits the ground. 3- Calculate the vertical velocity of the jumper, and total time of the jump if there was no air resistance. 4- Compare and comment on your results from 2 & 3 above.
Q2: Parachute Deployment:
Give a practical reason why the parachute should not be deployed immediately after jumping off the plane.
Q3 Sim :
Question 3: The Graph
Reset the simulation, and start a new jump.
This time, deploy the parachute at a safe altitude. (If you deploy the chute at high altitude, the jump will take longer to complete).
Check the [Show graph] checkbox to display the velocity - time graph,
Use the point tool and text tool to create and label the following points:
(IMPORTANT : DO NOT RESET THE SIMULATION AFTER ANSWERING Q1 TO Q5 BELOW)
On a different high altitude jump, another jumper with a total mass of 90 kg, jumped from 5,000 m. He deployed his parachute at 800 m. Calculate the magnitude of air resistance when he was 50 m above the ground.
