A woman throws an object of mass 500 g with a speed of `25 m s^(-1)` .
(a) What is the impulse imparted to the object ?
(b) If the object hitts a wall and rebounds with the half the original speed , what is the change in momentum of the object ?

Explanation

To solve the problem step by step, let's break it down into two parts as per the question.

### Part (a): Calculate the Impulse Imparted to the Object

1. **Identify the given values**:
- Mass of the object, \( m = 500 \, \text{g} = 0.5 \, \text{kg} \) (convert grams to kilograms)
- Initial velocity, \( u = 0 \, \text{m/s} \) (the object starts from rest)
- Final velocity, \( v = 25 \, \text{m/s} \)
