From a tower of height h, a particle is projected horizontally with velocity u, and another is thrown down with the same velocity u. If the time taken by these is t1 and t2, what is true?

Correct answer: B. t1 > t2

  • A. t1 = t2
  • B. t1 > t2
  • C. t1 < t2
  • D. t1 = 3t2

Explanation

This is the correct answer. In most cases, the particle that is thrown down (t₂) will reach the ground faster than the one projected horizontally (t₁). The horizontally projected particle initially has a horizontal velocity but no vertical velocity, so it takes longer to fall. The other options are incorrect because they do not consider the effects of initial velocity and vertical motion on the time taken for the particles to reach the ground.

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.
