A spring has an unstretched length of X cm. When it is hung with a load of 84 g, the spring has an overall length of 100 cm. If the load was only 25 g, then the spring would have been extended by an extra 6.5 cm (compared with if there had been no load applied).. A spring has an unstretched length of 12 cm. When an 80 g ball is hung from it, the length increases by 4.0 cm. Then the ball is pulled down another 4.0 cm and released. Draw a position. A spring has an unstretched length of 12cm. When an 80 g ball is hung from it, the length increases by 4.0 cm.Then the ball is pulled down another 4.0 cm and released. a) What is the spring constant? b) What is the period of the oscillation? Best Answer 83% (6 ratings). The object is released from rest when the spring is unstretched. If the object drops 10 cm before . physics. A 0.44-kg block is hung from and stretches a spring that is attached to the ceiling. A. A spring has an unstretched length of X cm. When it is hung with a load of 84 g, the spring has an overall length of 100 cm. If the load was only 25 g, then the spring would have been extended by an extra 6.5 cm (compared with if there had been no load applied).. Get the detailed answer: A spring has an unstretched length of 10 cm . It exerts a restoring force F when stretched to a length of 12 cm . For what total s ... It exerts a restoring. (1) A spring has a natural length of 16 cm. When it is stretched xcm beyond that, Hooke’s Law states that the spring pulls back with a restoring force F= kxdynes, where the constant kis called the spring constant, and represents the sti ness of the spring. For the given spring, 8 dynes of force are required to hold it stretched by 2 cm. How much. Apr 04, 2021 · A spring has an unstretched length of 12.0 cm. Its stiffness k is 8 N/cm. What load is needed to stretch the spring to a length of 15.0 cm?. An unstretched spring has a length of 10 centimeters.

then plug in our value for the spring constant k we calculated, the mass, and the initial stretch of the spring (which would be the stretched length 10 cm minus the unstretched length 3 cm. vf = s k m (xi) vf = v u u t 49 N=m 0:2 kg ((10¡ 3.0 ) cm) vf = 1.1 m=s 6. GRR1 6.P.029. A cart starts from position 4 in the flgure below with a velocity .... Chapter 10 Homework 1) A spring has an unstretched length of 10.0 cm. A 25 g mass is hung from the spring, stretching it to a length of 15.0 cm. If the mass is pulled down and released so that it oscillates, what is its spring constant? 1.6 N/m 16 N/m 4.9 N/m 49 N/m. Apr 04, 2021 · A spring has an unstretched length of 12.0 cm. Its stiffness k is 8 N/cm. What load is needed to stretch the spring to a length of 15.0 cm?. 100 g/cm3 B 140 100 g/cm3 C 120 180 g/cm3 D 140 180 g/cm3 6 A spring which obeys Hooke’s Law has an unstretched length of 10 cm. A load of 20 N is hung from the spring. The new length of the spring is 36 cm. What is the spring constant k of the spring? A 0.56 N / cm B 0.77 N / cm C 1.3 N / cm D 1.8 N / cm. The 12-kg slender rod is attached to a spring, which has an unstretched length of 2 m. If the rod is released from rest when \theta = 30°, determine the angular velocity of the rod the instant the spring becomes unstretched.. Explanation. Step 1. 1 of 3. When the spring is at its unstretched length, the displacement x = 0 x=0 x = 0. When the spring is stretched, x > 0 x>0 x > 0, and. when the spring is compressed, x < 0 x<0 x < 0. Remember the Hooke's law: the force required to hold the end of the spring at displacement x x x is F x = k x F_x=kx F x = k x. Find step-by-step Physics solutions and your answer to the following textbook question: A spring has an unstretched length of 10 cm. It exerts a restoring force F when stretched to a length of 11 cm. a. For what total stretched length of the spring is its restoring force 3f? b. At what compressed length is the restoring force 2F?. A block of mass m is connected to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane and are at rest. The spring is unstretched when a constant force F starts acting on the the block of mass M to pull it. Find the maximum extension of the spring.. The force of a spring needed to stretch/compress a spring is predictable and is given by Hooke's law: Spring's unstretched length 2x Applying a force F x stretches the spring by a distance x, with F = kx. 2x 2m F =k.x, in SI units, N The displacement of the spring's end if directly proportional the to applied force F Here, k is the spring constant,. 1.A spring has a natural length of 10 in. An 800-lb force stretches the spring to 14 in. (a)Find the force constant. Answer: Since 14 10 = 4 inches is 1 3 of a foot and since, by Hooke’s Law, F= kx, we know that 800 = k 1 3; so k= 800 3 = 2400. (b)How much work is done in stretching the spring from 10 in. to 12 in.?.
