The initial speed of an arrow is 15m/s
WebSep 17, 2015 · a) as the arrow was shot horizontally, the vertical component of its initial velocity will be zero. We will calculate the time that the arrow is in the air using the formula #s=ut+1/2at^2# as the initial vetical velocity is zero, u=0. Hence #33=1/2(9.81)t^2#. and #t=sqrt(66/9.81)=2.594# seconds. b) during the time that the arrow is in the air it …
