Concept explainers
An archer shoots an arrow at a 75.0 m distant target; the bull's-eye of the target is at same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull's-eye if its initial speed is 35.0 m/s? In this part of the problem, explicitly show how you follow the steps involved in solving projectile motion problems. (b) There is a large tree halfway between the archer and the target with an overhanging horizontal branch 3.50 m above the release height of the arrow. Will the arrow go over or under the branch?

- Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .arrow_forwardA projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one-sixth as large. How does the range of the projectile on the Moon compare with that of the projectile on the Earth? (a) It is one-sixth as large. (b) It is the same. (c) It is 6 times larger. (d) It is 6 times larger. (e) It is 36 times larger.arrow_forwardAn archer shoots an arrow at a 75.0 m distant target; the bull’s-eye of the target is at the same height as the release height of the arrow. (a) At what angle must the arrow be released to hit the bull’s-eye if its initial speed is 35.0 m/s? In this part of the problem, explicitly show how you follow the steps involved in solving projectile motion problems. (Feel free to use the “Range equation” referenced in the text.) (b) There is a large tree halfway between the archer and the target with an overhanging horizontal branch 3.50 m above the release height of the arrow. Will the arrow go over or under the branch?arrow_forward
- An arrow is aimed horizontally, directly at the center of a target 26 m away. The arrow hits 0.04 m below the center of the target. Neglecting air resistance, what was the initial speed of the arrow in m/s?arrow_forwardA baseball batter hits his home run ball with a velocity of 110 ft/s at an angle of 45° above the horizontal. If the ball hits the top of a screen at the 300 ft mark and bounces to the crowd, how high above the ground is the top of the screen?arrow_forwardThe highest barrier that a projectile can clear is 15.7 m, when the projectile is launched at an angle of 14.2° above the horizontal. What is the projectile's launch speed?arrow_forward
- A baseball batter hits his home run ball with a velocity of 110 ft/s at an angle of 45 degrees above the horizontal. If the ball hits the top of a screen the 300 ft mark and bounces to the crowd, how high above the ground is the top of the screen?arrow_forwardA ball is shot from ground level over level ground at a certain initial speed. The figure gives the range R of the ball versus its launch angle 8g. In the following questions, you will be ranking various points on the path. If multiple points rank equally, use the same rank for each, then exclude the intermediate ranking (i.e. if objects A, B, and C must be ranked, and A and B must both be ranked first, the ranking would be A:1, B:1, C:3). If all points rank equally, rank each as '1'. LINK TO TEXT Rank the three lettered points on the plot according to the ball's speed at maximum height, greatest first. R Point a Point b Point c 1. Greatest 2. Second greatest 3. Third greatestarrow_forwardAn artillery piece is on the edge of a cliff. This has a height of 12 meters. A vehicle is approaching at a constant velocity of 30 m/s. If the velocity of the projectiles is 700 m/s. What is the firing angle if you want to hit the vehicle when it is 200 meters from the cliff?arrow_forward
- An object is launched at a velocity of 20 m/s in a direction making an angle of 45° upward with the horizontal. a) What is the maximum height reached by the object? b) If the object has a time of flight of 2.9 s, what is the horizontal range of the object?arrow_forwardA stunt car leaves a 15° upward ramp at 35. The car jumps over a ravine and lands on the other side at 5 m S below the height from which it was launched. a) What is the maximum width of the ravine? (Answer: 77.5 m) b) What is the impact velocity of the car in magnitude and angle? (Answer: 36@21° below x)arrow_forwardJonah is reading a novel that describes an athlete participating in an archery competition. The athlete is 186 cm tall and hits an amazing shot where they fire the arrow completely horizontally and it lands 51 m away from them. 1) neglecting air resistance and drag, what must the initial speed of the arrow be? 2) if the arrow was instead fired at an angle of 45°, how far would it have travelled if it was launched at 187m/s?arrow_forward
