Problem 31DQ

When does a baseball in light have an acceleration with a positive upward component? Explain in terms of the forces on the ball and also in terms of the velocity components compared to the terminal speed. Do ?not? ignore air resistance.

Step-by-Step Solution:

Solution 31DQ Step 1: When the base ball is launched in air, it has maximum force offered by air resistance say F 1 pointing downwards and the as the baseball goes up , this air resistance reduces and reaches to zero at the maximum height That is at maximum height, the air resistance is F1= 0 The gravitational force is acting vertically downwards on the given by F ,g The acceleration is negative when the ball is going up as the both the forces are directed downward Step 2 : As the ball starts moving downward , it will be along the direction of the gravitational force and air resistance , hence the acceleration of the ball towards the ground will be positive Thus the base ball will have positive acceleration, at the point when it starts moving towards the ground or when it has reached its maximum distance vertically
