A bee flies east at a speed of 1.00 m/s relative to air. The wind has a speed of 5.0 km/hr with respect to Earth in the direction 25° west of south. How long will it take the bee to cross a field that is 500m wide? 18 min 16 min 6.3 min 20 min The bee can not cross the field.
A rock was thrown horizontally from a 100.0 m high cliff. It strikes the ground 90.0 m from the base of the cliff. a) At what speed was it thrown? b) How long did it take to hit the ground. c) Neglecting wind resistance, which component of velocity is affected by gravity VERTICAL or HORIZONTAL? d) Sketch the trajectory of the rock as it falls to the ground and include the velocity vector at the beginning, midway down, and just before striking the ground. e) After you determine the total time in the air, you can then determine the final vertical velocity vector combined with the horizontal velocity determined earlier. Use these vectors to determine the resultant velocity vector just before landing. Recall using Pythagorean theorem to find the magnitude of the velocity vector and trigonometry for the angle below the horizontal that the resultant vector strikes at.
