On the surface of the moon , a cricket ball is hit at some angle with the horizontal . As the ball traveles through vecuume , determine which of the quantities will not change? (a) speed , (b) acceleration , (c) horizontal and vertical components of velocity and (d) resultant velocity .

Explanation

To determine which of the quantities will not change when a cricket ball is hit at an angle on the surface of the moon, we need to analyze the motion of the ball in a vacuum. Let's break down the problem step by step:

### Step 1: Understand the Environment
- The ball is projected on the moon, where there is no atmosphere. This means there are no resistive forces acting on the ball, such as air resistance.

**Hint:** Consider how the absence of air affects the motion of the ball.

### Step 2: Identify the Forces Acting on the Ball
