A place-kicker must kick a football from a point 36 m (about 40 yards) from the goal, and half the crowd hopes the ball will clear the crossbar, which is 3.1m high. Projectile motion problems, or problems of an object launched in both the x- and y- directions, can be analyzed using the physics you already know. Figure 4.12 (a) We analyze two-dimensional projectile motion by breaking it into two independent one-dimensional motions along the vertical and horizontal axes.
