Answer:
Given: A body is thrown vertically up from ground with initial velocity 10 m/s.
To Find: Calculate the maximum height attained by the body of air friction force varies with velocity as |F| = mv²
Solution: If a body is moving vertically downwards or upwards, it experiences a downward acceleration due to the gravitational force of the earth. This is called acceleration due to gravity and is denoted by the symbol . Strictly speaking is not a constant, but varies from place to place on the surface of the earth and also with height. However the variation of is so small that it can be neglected and can be considered as a constant unless very large heights are involved. Therefore, we can use the equations of motion for constant acceleration.
