A :-) For this question , we should apply v = u + at Given - u = 40 m/s a = 2.5 m/s^2 t = 12 sec Solution - v = u + at v = 40 + 2.5 x 12 v = 40 + 30 v = 70 m/s
.:. The new speed is 70 m/s. ( speed = velocity ).
Humans invented agriculture between 7,000 and 10,000 years ago, during the Neolithic era, or the New Stone Age. There were eight Neolithic crops: emmer wheat, einkorn wheat, peas, lentils, bitter vetch, hulled barley, chickpeas, and flax.
