L=vₒ²sin2α/g=50²不in74º/9.8=245.2 m
this question is multiple choice there are choices and this answer is not among them :(
Upward motion (from the start point to the highest point)
v=v(0y)-gt ,
v=0
t= v(0y)/g=v(0) 不inα/g
the horizontal range is
L=2夫(x) 付=2夫(0) 苗osα夫(0) 不inα/g= =v²(0) 不in2 α/g.
This is correct answer (both formula and calculation).
