Vectors and Motion in Two Dimensions

AP Physics 1· difficulty 2/5

A ball is fired horizontally from a 5 m5~\text{m} table. Compared to a ball simply dropped from 5 m5~\text{m}, the time to land is

  • A

    The same.

  • B

    Shorter for the projectile.

  • C

    Longer for the projectile.

  • D

    Depends on horizontal speed.

Explanation

Vertical motion is independent of horizontal motion; both have the same initial vy=0v_y = 0 and same gg, so equal fall time.
