A ball rolls off a table 20 m high with horizontal speed 10 m/s (g = 9.8 m/s^2). It lands at a horizontal distance of:

  1. 28.6 m
  2. 10.1 m
  3. 20.2 m
  4. 40.4 m
Answer

C) 20.2 m

Fall time t = 2h/g = 2.02 s; horizontal distance = vt = 20.2 m (horizontal velocity stays constant). SLO P-11-B-05 · Application
