The big deal with 2-dimensional kinematics is that we can break most problems back down into one dimensional problems if the acceleration is constant. For example, vx = vx0 + axt where vx0 is the x component of the velocity at time t=0s, vx is the x component of the velocity at time t, and ax is the x component of the acceleration. In the vertical direction, the same formula is valid for all of the y components: vy =...
