Two soccer players kick a soccer ball back and forth along a straight line. The first player kicks the ball 15 m to the right to the second player. The second player kicks the ball to the left weakly; it only moves 3.5 m before stopping. (Consider the right to be the positive direction. Where applicable, indicate the direction with the sign of your answer.)
(a) What is the total distance that the ball moved?
m
(b) At the end, what is the displacement of the ball (from the
first player)?
m

You kick a soccer ball straight upwards into the air. Your friend times the ball and it takes a total of 3.31 seconds for the ball to go up, come down, and return to the point where you first kicked it. What was the ball's initial velocity (in m/s) immediately after the kick? (Use g = -9.8 m/s2 and round to 3 significant figures) I believe it's 16.2 m/s?? Not sure if I'm right though.

As shown in the diagram below, a soccer player kicks a ball directly toward the goal along a displacement vector r, which has a length of 9.4 m and a direction 30 degrees east of south. Alternatively, she could have kicked it to a second player standing directly in front of the goal along a displacement ry, who could have then kicked it to the goal along a displacement vector rx as...

1. A soccer player can kick a ball with maximum initial speed 10 m/s. She kicked the ball at different angles to check how the horizontal distance to the point the ball hits the ground changes with the angle the ball is kicked. Calculate the horizontal distance for different angles and draw a graph of the horizontal distance versus the angle θ with the ground. What is the angle at which the distance is maximum? Can you explain why there...

A busy chipmunk runs back and forth along a straight line of acorns that has been set out between its burrow and a nearby tree. At some instant, it moves with a velocity of −1.05 m/s. Then, 2.23 s later, it moves with a velocity of 1.51 m/s. What is the chipmunk's average acceleration during the 2.23 s time interval?
