kinematics in 2 dimensions

It's "floats" instead of "that float", and "affected". Good job using affect instead of effect though.

y is easy. To get x, you integrate v_x = ky by obtaining its antiderivative, .5ky^2, and doing y_final minus y_initial. y_initial is of course 0, and y_final simply means 1.2 * 15 = 18 m. If you plug 18 into .5ky^2 you get 243 m. So I say the answer is (243, 18) but I could be wrong since I am slightly buzzed.
