A nylon string (modeled as a spring) with original length 20 cm, is pulled by a force of 10 N. The change in length of the string is 2 cm.  a) what is the spring constant?  b) determine the magnitude of force if the change in length is 6 cm.

Hello, I need some help with this problem?

A 273 g mass causes a 0.29 m change in length when hanging from a particular spring. Find the associated spring constant. O941.38 N/m O 9,226 N/m 92.26 N/m 0.941 N/m

A 0.81-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched length triples. What is the mass of the second block? Unstretched length m1 X2 = 3x1 m1 m2 Number Units

A mass (M) is attached to a spring that is (X) m long when unstretched with a spring constant of (k) N/m. What is the maximum speed of the mass? Looking for the equation in terms of M, X and k thank you

Fish are hung on a spring scale to determine their mass. a. What is the force constant of the spring in such a scale if it the spring stretches 11.00 cm for a 13.0 kg load? b. What is the mass of a fish that stretches the spring 7.00 cm? c. How far apart are the quarter-kilogram marks on the scale?

As shown below, a 3 kg block on a frictionless horizontal surface is attached to a cable and a 526 N/m spring. The block is in equilibrium (Fnet = 0) and the cable has a tension of 16 N. Determine the normal force on the block and how much the spring stretched. FN l=| x

A spring with a force constant of 300 N/m is attached to and compressed by a 4 kg mass to a compression of 1.5 m.  The mass is released from rest.  The surface is frictionless. How much time does it take the mass to return to the equilibrium position the first time after release? What is the velocity of the mass when it returns to the equilibrium position the first time after release?  Include sign.

A block with a mass m = 2.5 kg is pushed into an ideal spring whose spring constant is k = 4520 N/m. The spring is compressed x = 0.066 m and released. After losing contact with the spring, the block slides a distance of d = 2.25 m across the floor before coming to rest. a. Write an expression for the coefficient of kinetic friction between the block and the floor using the symbols given in the problem statement and g (the acceleration due to gravity). (Do not neglect the work done by friction while the block is still in contact with the spring.)

You have a light spring which obeys Hooke's law. This spring stretches 2.24 cm vertically when a 2.40 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) Answer____________ N/m (b) the distance (in cm) the spring stretches if you replace the 2.40 kg object with a 1.20 kg object Answer____________ cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.50 cm from its unstretched position Answer____________ J
