Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Problem 4 134. Astronomy About 65 million years ago an aster- oid struck Earth in the area of the Yucatan Peninsula and wiped out the dinosaurs and many other life forms. Judging from the size of the crater and the effects on Earth, the asteroid was about 10 km in diameter (assumed spherical) and probably had a density of 2.0 g/cm³ (typi- cal of asteroids). Its speed was at least 11 km/s. (a) What is the maximum amount of ocean water (originally at 20 °C) that it could have evaporated?
