please write down the formula you used and all the steps! thank you! )
A cannon elevated at some angle (unknown) fires a shell with some initial speed v(unknown) that has a range R when fired over level ground (see Figure (a)). (a) No Explosion During a test fire, a shell explodes at the top of the trajectory into two unequal mass fragments. The shell explodes in such a manner that neither fragment experiences a change in momentum in the y-direction. However, 22% of the shell (m) continues onward and the other fragment (m) falls straight down. Determine the distance D (in terms of R) that the forward moving fragment lands from the cannon (see Figure (b)).
