Question
Alert! Alert! An asteroid is spotted heading for earth.Measurements of the Asteroid estimate the mass to be 100,000,000 kgand a velocity of 10000 m/s. You and your crew are our only hope.You have to fly to the asteroid and try to stop it with our supership. If you position yourself at the front of the asteroid andland on the asteroid, maybe you can use our thrusters to slow theasteroid. What force would you need to stop the asteroid in anexplosion that lasted 1 sec?
Do we have that type of power available in the ship if we canconcentrate the force into 1 sec?
There is a special button on the ship that gives an extra100x10^9 N but it causes the ship to self destruct. Will this beenough to save the planet?
What do you do?
Explanation / Answer
The rate of change in momentum is the force applied. F=(mv-mu)/t F=(10^8*10^4-0)/1 F=10^12N Hence we get by it.Related Questions
