A ball falls from a table top with initial horizontal speed $V_0$. In the absence of air resistance, which of the following statement is correct
Show Hint
In projectile motion, horizontal and vertical motions are independent.
Updated On: May 1, 2026
- The vertical component of the acceleration changes with time
- The horizontal component of the velocity does not change with time
- The horizontal component of the acceleration is non zero and finite
- The time taken by the ball to touch the ground depends on $V_0$
- The vertical component of the acceleration varies with time
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Projectile motion:
• Horizontal acceleration = $0$
• Vertical acceleration = $g$ (constant)
Step 1: Horizontal motion.
No force acts horizontally $\Rightarrow$ velocity remains constant. \[ v_x = \text{constant} \]
Step 2: Vertical motion.
Acceleration due to gravity is constant. \[ a_y = g \]
Step 3: Check options.
Only correct statement: \[ \text{Horizontal velocity does not change} \]
