HOMEWORK SUBMITTED IN WRONG FORUM, SO NO TEMPLATE I uploaded an image of the problem, it seems to be fairly straight forward. However, my textbook indicates the answer as being 6 m/s, I am consistently getting 3 m/s. Any help would be appreciated!! Because there is no air resistance, the horizontal velocity is constant. 2ax+vo^2=vf^2 We can set the Vo equal to zero, find the required speed to achieve .45m vertically. We find Viy=2.97m/s vf=at 2.97=at 2.97/9.81=.3 seconds Horizontal speed (distance over time)- constant speed .25/.3=.833 m/s (.833^2+2.97^2)^.5=3m/s I know that the height and length indicated in the problem yield a angle of 61 degrees, however, this information still does not yield the correct answer.
