Drake moves horizontally at the exact same time it takes to move vertically. This means that I can use horizontal motion to calculate time, and then use that amount of time in vertical motion to find its final vertical position.
When Drake makes his jump, he has to rise to a vertical position of zero meters; This is the location of the ramp and where I set the source. If this final value is less than zero meters, it will land Down Aircraft. And that would be bad.
Determining horizontal motion is not very difficult. Since it has a constant velocity, I can find its final horizontal position with the following equation:
Check it out: I know the starting x-position (x1 = 2.4 m) and the final x-position (x)2 = 0 m) so I can use x-velocity to solve the time it takes to complete the jump. (He is moving to the left, so it will be negative 3.37 m / s.)
Notice that we don’t see the full jump in the trailer, however, if we do, it will take 0.71 seconds to reach the rear ramp of the aircraft.
Now, I can use this time and plug in the vertical kinematic equation. This gives a final y-position Negative 1.79 m.
It is less than zero, so there is nothing but air beneath it. And remember: it’s bad.
We haven’t finished yet, but it’s worth taking a second to think about why it even ended Low Than he started. This is because although its initial velocity is positive (upward), the jump takes so long that the gravitational force stops its upward motion and forces it to go down faster and faster.
What about moving air?
When you stick your hand out the window of a moving car, you can feel something pushing you back. This is the interaction between the air molecules around your hands and the car – we call it air resistance. The amount of force you feel depends on the relative speed of the hand with the wind and the size and shape of your hand. At very high speeds, this wind resistance can be significant.
Let’s say the plane has a flying speed of 120 miles per hour — I like that value because it is equal to the terminal velocity of a human skydiver. When someone falls through the air for a while, the gravitational force increases their speed. But this increase in velocity also increases the resistance of the upward wind. Not too long after a jump, at some point, the upward wind resistance is equal to the downward gravitational ball. This means that the total energy is zero and the diver is no longer accelerated. Instead, they now move at a constant speed. We call that terminal velocity. Of course, humans can still adjust their bodies and communicate with the wind to get around and run techniques কারণ which is why skydiving is still fun.
