- -23A surgeon is using material from a donated heart to repair a patient's damaged aorta and needs to know the elastic characteristics of this aortal material. Tests performed on a 16.0 em strip of the donated aorta reveal that it stretches 3.75 cm when a 1.50 N pull is exerted on it. (a) What is the force constant of this strip of aortal material? (b) If the maximum distance it will be able to stretch when it replaces the aorta in the damaged heart is 1.14 cm, what is the greatest force it will be able to exert there?A person rolls a bowling ball down a rapp, towards a relaxed spring. The ball is rolled with an initial speed of 1.25 m/s from a ramp at a height (h) of 1.80 m. The mass of the ball is 0.600 kg. Determine the elastic constant for the spring if the spring's length is compressed by 16.0 cm during the stopping of the bat motion. Edt Formul Table 12 Purph BIVAL ONOM
- 11 of 24 > Constants Periodic Table A block of mass m is placed in a smooth-bored spring gun at the bottom of the incline so that it compresses the spring by an amount c. The spring has spring constant k. The incline makes an angle 0 with the horizontal and the coefficient of kinetic friction between the block and the incline is u. The block is released, exits the muzzle of the gun, and slides up an incline a total distance L. (Figure 1) Part A Find L, the distance traveled along the incline by the block after it exits the gun. Ignore friction when the block is inside the gun. Also, assume that the uncompressed spring is just at the top of the gun (i.e., the block moves a distance rc while inside of the gun). Use g for the magnitude of acceleration due to gravity. Express the distance L in terms of xc, k, m, g, µ, and 0. • View Available Hint(s) ?

Luckily, he has his trusty toy dart gun whose spring has a 110 N/m spring constant. He loads his 7.2 gram suction cup dart, compresses the spring 4.0 cm, takes vertical aim at the cabin ceiling, and shoots. The suction cup dart flies 1.47 meters above its initial spring-compressed position. What is Spiff's altitude above earth? a

Qualitatively describe what occurs to the energy of the system once the object is released? (Hint: Consider what occurs as the object falls, encounters the spring, and if it will go back up again!)
