Sending spaceships to the outer regions of the solar system requires large energies. The slingshot effect is a frequently used
method for speeding up spaceships without using much rocket fuel. To use this effect, the spaceship is diverted to pass around
one of the inner planets (such as Venus). If the spaceship is sent in the right direction, it will reach to greater speeds after it
passes around the planet. You will see the effect at play in this question.
A spaceship is sent with an initial velocity of is = (30 - j – 20 - î) km/s towards a planet. The planet is moving with velocity
úp = 20i km/s. After the encounter with the planet, the spaceship emerges to be moving along the +r direction (with a final
velocity of the form is = vgi). Find the final speed of the spaceship in units of km/s.
= 40
km/s. 40
Incorrect answer.
Hint 1: This is an elastic "collision". When you hear the word collision, you usually imagine something that happens quickly; in
contrast this collision happens…
Need help with this, thanks :)
One particle has mass m and a second particle has mass 2m. The second particle is moving with speed v and the first with speed 2v. How do their kinetic energies compare?
