Question

A baseball has 5.8kg*m/s momentum before being hit by the bat. After being hit it has 6.79 kg*m/s in the opposite direction. What is the magnitude of the impulse applied to the baseball?​

Answer 1

Answer:

0.99kgm/s

Explanation:

Given parameters:

Initial momentum  = 5.8kgm/s

Final momentum  = 6.79kgm/s

Unknown:

Magnitude of the impulse applied to the baseball  = ?

Solution:

To solve this problem;

 The impulse applied to the baseball can be found by using the expression below:

 Impulse  = Final momentum   -   Initial momentum

Impulse  = 6.79kgm/s - 5.8kgm/s  = 0.99kgm/s
