During a football game Aiden kicks a ball from the ground at the 30-yard line. He gives the ball an initial speed of 20 meters per second, at an initial angle of 36.9 degrees. a. One second after the kick how high is the ball above the ground measured in feet? b. How far away will the ball land on the ground measured in yards?
1. A ball is thrown upwards with an initial velocity of ; = 44 m/s at an angle of above the horizontal. It travels a distance Ar = 75 m in the horizontal direction and lands at its original height. What is 0? (Hint 1: examine the ball's motion in both the x and y directions. Hint 2: you may need to use that sin(0) cos(0) = (1/2) sin(20). Hint 3: There are two solutions to this problem; try to find both.) Take g = 9.81 m/s² and show all your work.
6. A skilled golfer hits a ball so that it just clears the top of a tree and onto an elevated green as shown. The tree is horizontally a distance, x = 18.3 m from the golfer and its height is 10.2 m. a) Determine the golf ball's initial y-velocity so that the maximum height it reaches is the same as the height of the tree. b) Determine the time it takes for the ball to climb to that maximum height c) Using the time information in b, determine the golf ball's initial x-velocity d) Using your answer to a) and c), determine the magnitude and direction of the golf ball's initial velocity. e) If the golfer was to hit the ball over level ground so that it went as far as possible, at what angle would he want to hit the ball? Explain.
Your nephew got a Nerf Bazooka gun for Christmas, so you take it outside to play with it (just like my uncles did when I was little). The bazooka is on your shoulder, 1.5 m above the ground. You aim the gun 25° above the horizontal and the big, foam projectile leaves the gun with an initial velocity of 36 m You accidentally aim the bazooka at a tree that is a horizontal distance of 27 m away. How long does it take for the projectile to hit the tree? t = How high (above the ground) in the tree does the projectile get stuck? hfinal = m Imagine you were more clever and aimed into an empty field with no obstructions. You can control how fast the projectile leaves the gun by pumping more times or fewer times (more pumps = faster projectile). What are TWO ways you could increase the amount of time that the projectile is in the air?
6. A person kicks a soccer ball such that it leaves the ground with an initial velocity of 20.0 m/s at an angle of 18.0° above the horizontal. The ball travels 9.00 meters horizontally where it then arrives at the goal that has a height of 2.13 m. a) Assuming the goalkeeper is not able get to the ball, does it score a goal? b) If the ball has a diameter of 0.220 m, how far above or below the top of the goal is the nearest part of the ball? c) What is the velocity of the ball when it reaches the goal? Answers: (a) GOALLLLLL!!! (b) 8.27 cm below the top, (c) 19.1 m/s @ 4.64°
A ping pong ball rolls at a speed of 0.60 m/s toward the edge of a table which is 0.80 m high. The ball rolls off the table. a) How long is the ball in the air? b) How far out from the point directly below the edge of the tabletop does the ball hit the floor?
14. Johnson is throwing a football in his back yard. He throws the ball at 30.00 m/s at an angle of 37 degrees abovethe horizontal. The ball leaves his hand when it is 1.75 m above the ground. a) What is the maximum height the ball reaches above the ground? b) The ball lands on a tree that is 10.0 m tall. How far is Johnson from the tree? c) If that pesky tree wasn’t in the way, with what speed would the ball have impacted the ground? (Do not use i and j vectors)
