Notice that there are two unknowns in the vertical motion: (1) the initial y velocity voy and (2) the magnitude of the gravitational acceleration g. Therefore, in general, you will get a set of two equations to solve for the two unknowns Choose the two equations below that you can use to solve for g and voy for projectile B. O 8m = voy(1.58) – g (1.125s²)
