5. Projectile motion. You make a goal kick in a soccer game while you are 1.5 m away from the goal entrance. As the ball leaves your foot, it makes an angle of 55° with the ground and travels at 6 m/s. If the top of the goal is 3.0 m high, does your shot make it into the goal?
Whether or not it makes it into the goal, is it traveling up or down when it reaches the goal? Plot each of the following graphs for the time interval between when the ball leaves your foot and when the ball crosses the goal line: xposition vs. time, yposition vs. time, xvelocity vs. time, yvelocity vs. time, xacceleration vs. time, yacceleration vs. time.
