A ball rolls off a table 45 m high with horizontal speed 15 m/s (g = 9.8 m/s^2). It lands at a horizontal distance of:

  1. 64.3 m
  2. 45.5 m
  3. 90.9 m
  4. 22.7 m
Answer

B) 45.5 m

Fall time t = 2h/g = 3.03 s; horizontal distance = vt = 45.5 m (horizontal velocity stays constant). SLO P-11-B-05 · Application
