A bullet is fired with a gun from tower horizontally with a velocity 400 m/s. at the same time, a stone is dropped from the same tower.
Correct answer: C. Both will reach the ground at the same time
- A. The stone will reach the ground first
- B. The bullet will reach the ground first
- C. Both will reach the ground at the same time
- D. None of these
Explanation
When a bullet is fired horizontally and a stone is dropped from the same height, both objects are influenced by gravity equally. Since both the bullet and the stone start with an initial vertical velocity of zero and are accelerated by gravity at the same rate (approximately 9.81 m/s²), they will hit the ground simultaneously. The horizontal motion of the bullet does not affect the time it takes to fall to the ground. Therefore, the correct answer is that both will reach the ground at the same time.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
