Problem 55E
CP An asteroid with a diameter of 10 km and a mass of 2.60 X 1015 kg impacts the earth at a speed of 32.0 km/s, landing in the Pacific Ocean. If 1.00% of the asteroid’s kinetic energy goes to boiling the ocean water (assume an initial water temperature of 10.0o C), what mass of water will be boiled away by the collision? (For comparison, the mass of water contained in Lake Superior is about 2 X 1015 kg.)

ANSWER:Solution 55E
Step 1 :
Mass of asteroid
Diameter of asteroid
Velocity of asteroid
Initial temperature of water
Mass of lake superior
We need to find the mass of water which would get heated due to kinetic heat of asteroid
