PRACTICE / Unequal launch and landing heights

A horizontal launch from a ledge

A small ball leaves a 20 m high ledge horizontally at 8 m/s.

How far from the base does it land?

Organize the givens & assumptions
  • h = 20 m
  • ux = 8 m/s
  • uy = 0

g = 10 m/s²; no drag; horizontal launch has zero initial vertical velocity; level ground below.

  1. A16 m16\ \mathrm m
  2. B8 m8\ \mathrm m
  3. C32 m32\ \mathrm m
  4. D6.4 m6.4\ \mathrm m
