Now usually, a squirrel will jump off a bird feeder that starts to spin—but not the one in this viral video.But what is the force-paired object pushing on the squirrel?When you drop that apple, the gravitational force increases its speed as it falls, thus increasing its momentum.
Avast Antivirus Shuts Down Its Shady Data-Selling BusinessKudos this week to Motherboard and PC Mag, who jointly further exposed the shady practices of security company Avast.By the end of the week, Avast had decided to stop collecting and selling user data, and to wind down Jumpshot altogether.
Now, if we put this vertical acceleration together with the fixed horizontal velocity , we get something special, called projectile motion. On the next jump, I get a vertical acceleration of –6.074, which is closer, but you can see that the fit is pretty janky.
To estimate the acceleration, we can look at the angular size of the back of the Falcon as it moves away. All I need to do is measure the position of the sides of the Falcon and use that to calculate the angular size in each frame of the video during the jump to hyperspace.
A Physics Analysis of Every Jedi Jump in All of Star Wars. For these Jedi jumps in Star Wars, it's plausible to estimate the distance scale by looking at things like Ewan McGregor (height of 1.78 meters) or Liam Neeson (height of 1.93 meters).
For Rey jumping over (I assume she makes it) a TIE fighter, I'm just going to look at her vertical motion. There is some type of TIE fighter zooming toward Rey. You would think her goal is to jump over the spacecraft, but who really knows.
If I assume he jumps like a normal human with an upward speed of 3 m/s (this would give a 0.6 second hang time), then the gravitational field would be 1.4 N/kg.
Burger King’s One-Cent Whopper Offers a Taste of the Robocar FutureIn a world with more ride-hailing and self-driving tech, ads that have always been relegated to billboards can move into the car.At first bite, it seems no more than a clever way to boost sales at the expense of a competitor.
But both Uber and Lime say they’ve been snubbed, and that they want to expand service to more lower income New Yorkers.A mock-up of Lyft's branded dockless bikes, which the company says it might deploy in cities all over the US.
GETTYA two metre jump could see a host of major cities be partially submergedCo-author John Fasullo, a climate scientist at the National Center for Atmospheric Research, said: "This study highlights the important role that can be played by satellite records in validating climate model projections.”If the calculations are correct, it would mean that sea levels could rise by almost one metre by 2100, which would be devastating for island countries around the globe.
