R= 4H b. 4R =H
2H = R
d. None of these
A cannon ball has a range R on a horizontal plane, such that the corresponding possible maximum
heights reached are H, and H2. Then, the correct expression for R is

Ireally just need to get finished with precal! i’m really sorry i have to do this! hope this !

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
