An archery bow is drawn a distance d 0.28 m and loaded with an arrow of mass m a spring with a spring constant of k 154 N/m, and the arrow flies with negligible air resistance. To simplify your work, let the 0.084 kg. The bow acts as gravitational potential energy be zero at the initial height of the arrow. 220 Part (a) How fast, in meters per second, will the arrow be traveling as it leaves the bow? aila...
An 85-g arrow is fired from a bow whose string exerts an average force of 110 N on the arrow over a distance of 83 cm . What is the speed of the arrow as it leaves the bow? Express your answer to two significant figures and include the appropriate units. PLEASE BOX ANSWER.
A 28 g ball is shot from a spring gun whose spring has a force constant of 367 N/m. The spring can be compressed 3 cm. How high will the ball go if the gun is aimed vertically? The acceleration of gravity is 9.81 m/s 2 . Assume that at the end of the barrel, the spring’s displacement and the ball’s height are each zero. Answer in units of m.
An 82 g arrow is fired from a bow whose string exerts an average force of 95 N on the arrow over a distance of 85 cm. What is the speed of the arrow as it leaves the bow? Express as m/s
The massless spring of a spring gun has a force constant k = 0.04 N/cm. When the gun is aimed vertically, a 19 g projectile is shot to a height of 5.0 m above the end of the expanded spring. (See below.) How much was the spring compressed initially? (Find d, in meters.)
A block with mass m = 1.5 kg compresses a vertically oriented ideal spring a distance deltaY= 15 cm from its uncompressed state. If the spring has a constant k = 750 N/m find the following: a. The highest point the block reaches (measured from its starting position. b. The maximum velocity of the block.
§A favorite circus act is the “human cannonball,” in which a person is shot from a long barrel. §Before the Italian Zacchini brothers invented the compressed air powered cannon to shoot human cannonballs in the 1920s, the Englishman George Farini used a spring-loaded cannon to do the same since the 1870s. §Suppose we want to recreate the spring-loaded human cannonball act with a spring inside of a barrel. §Suppose the barrel is 4.00 m long, and you have room to...
016 10.0 points A(n) 69.7 g ball is dropped from a height of 69.9 cm above a spring of negligible mass. The ball compresses the spring to a maximum displacement of 4.7532 cm. The acceleration of gravity is 9.8 m/s2 Calculate the spring force constant k Answer in units of N/m.
refer to picture. A 10.0 g bullet is shot straight up and has initial kinetic energy of 2.50 kJ. The speed of the bullet when it is halfway to maximum height is equal to a. 250 m/s 354 m/s 500 m/s 707 m/s 1,000 m/s re constant of 2.990 N/m. The work done in stretching the spring
9) A 500-g block is dropped from a height of 60.0 cm above the top of a vertical spring whose stiffness constant is k = 120 N/m as shown in the figure below. Find the maximum compression. (You will need to solve a quadratic equation.) 60 cm
