Aball bearing is fired straight up at a speed of 40m/s. calculate the time during which it is in the air. ignore air resistance.
i have been given the following equations:
![v = u + at\\s = 1/2(u + v)t\\s = ut + 1/2at^2\\s = vt-1/2at^2\\v^2 = u^2 + 2as](/tex.php?f=v = u + at\\s = 1/2(u + v)t\\s = ut + 1/2at^2\\s = vt-1/2at^2\\v^2 = u^2 + 2as)
an explanation would be very much appreciated! you.
