so be careful to such questions
and it is easy to change the data to become new questions. Dx = V*t, t = Dx/V = 65 / 178 = 0.349 s. Dy = 0.5g*t^2 = 4.9*(0.349)^2=0.592 m.= Miss distance. b. Dx = Vo^2*sin(2A)/g = 68 m, (175)^2*sin(2A)/9.8 = 68, Divide both sides by (176)^2: sin(2A) / 9.8
There are some basic formula which are very important
Can you the full working out for this question above...
