A slingshot is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame held in the non-dominant hand, with two natural-rubber strips or tubes attached to the upper two ends. The other ends of the strips lead back to a pocket that holds the projectile. The dominant hand grasps the pocket and draws it back to the desired extent to provide power for the projectile—up to a full span of the arm with sufficiently long bands.
Other names include catapult (United Kingdom), gulel (India), getis / gulel (Nepal), kettie (South Africa), or ging, shanghai, pachoonga (Australia and New Zealand).
If you use the most suitable elastic material known today (in terms of elastic properties, the way it's applied and the manufacture of it), how huge (at least theoreticaly speaking) should sligshot be in order to be able to fire a projectile (a steel ball of any diameter you find suitable) so it...
NASA often uses the gravity of a planet to slingshot a probe on its way to a more distant planet. The interaction of the planet and the spacecraft is a collision in which the objects do not touch. How can the probe have its speed increased in this manner?
This problem confuses me, I want...
Voyager 2 used a slingshot maneuver to approach Saturn and then move off in the opposite direction.Voyager 2 approached Saturn with a velocity of 12 Kms^-1. (relative to the sun). The orbital speed of Saturn is 13 Kms&-1. The question is what was Voyager 2's speed after the slingshot encounter...
when space probes pass planets and gains speed via the slingshot effect; where does the extra energy come from? will it not violate the laws of thermodynamics? I know it doesn't but why?
Spacecraft voyager 2 (of mass m and speed v relative to the sun) approaches the planet Jupiter (of mass M and speed v_J relative to the sun). The spacecraft rounds the planet and departs in the opposite direction. What is its speed, relative to the sun, after this slingshot encounter, which...
i have a test tomorow and I am having trouble with these questions can some one pls check over my answers?
1. a slingshop shoots a 12g stone at 36m/s. It goes in an arc and at the top of the arc it is going at 14m/s. How high is it at this point?
12g=0.012kg
36m/s=v1
14m/s=v2
Ek=1/2mv2...
Hi,
Please help me to understand this question of the problem:
A boy wants to knock down a coconut with a rock and his slingshot. He observes that the coconut is about 3.0m above his slingshot and the tree is 4.0m away along the ground.
He knows from experience that the release speed of his...
lets assume that a base was constructed on the moon for the purpose of launching spacecraft .
if spacecraft were dropped off the moon toward the earth, with a horizontal velocity component such that they would then slingshot around the earth, could the initial velocity provided by a...
Hey,
for a physics project, i have the task of building a manpowered cart that will fit one person in and slingshoot a regular volleyball a whopping 8-10m! the basic plan so far is to have the cart approximately 5'3 in length and just wide enough to fit the person it. The task is to hit a...
A slingshot consists of a light leather cup containing a stone that is pulled back against two parallel rubber bands. It takes a force of 15 N to stretch either one of the bands 1.0 cm. A)What is the potential energy in the two bands together when a 47g stone is placed in the cup and pulled...
Gravitational slingshot
How does this work exactly? Where does my analysis go wrong?
I know it is used to speed satellites up, but its name alludes to a permanent improvement in speed. The way I see it, you would get a slight benefit in journey time as long as the satellite is within the...
