You have a light spring which obeys Hooke's law. This spring stretches 3.28 cm vertically when a 2.70 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) N/m (b) the distance (in cm) the spring stretches if you replace the 2.70 kg object with a 1.35 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 7.70 cm from its unstretched position J

ull T-Mobile LTE 5:27 PM O 21% O Done 11 of 11 A spring 1.50 m long with force constant 460 N/m is hung from the ceiling of an elevator, and a block of mass 14.0 kg is attached to the bottom of the spring. (a) By how much is the spring stretched when the block is slowly lowered to its equilibrium point? (Enter the magnitude only.) (b) If the elevator subsequently accelerates upward at 1.68 m/s², what is the position of the block, taking the equilibrium position found in part (a) as y = 0 and upwards as the positive y-direction. (Indicate the direction with the sign of your answer.) m (c) If the elevator cable snaps during the acceleration, describe the subsequent motion of the block relative to the freely falling elevator. What is the amplitude of its motion? Additional Materials OeBook

1. On my telemark skis, each ski binding has a set of 15cm long springs which get stretched out at the start of a ski turn and then released when the turn ends. If it takes 200N of force to stretch these springs 5cm beyond their natural length. a) Use Hooke's Law, F(x) = kx, to determine the specific force function for these springs including solving for a specific value for the spring constant k b) On a steep ski run, in the middle of a ski turn, I must deepen my ski turn to keep my speed in check as the slope rolls over. How much work must I do to stretch these springs from 2cm beyond their natural length, early in the turn, until they are 5 cm beyond their natural length, toward the end of the turn?

What's the answer?

When a spring is extended by 50 mm with the application of a force of 10N, the spring constant is 200N/m. What is the magnitude of the force required to extend the same spring by 80 mm? (in units of N)

An object is hung vertically from a stretchy material and causes it to stretch 4.0 cm as a result. Suppose the stretchy material has been calibrated according to the following trendline equation: F_sp = (90.8 N/m) * x - (1.94 N) What is the mass of the object?

A 0.46 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?

You need to make a spring scale to measure the mass of objects hung from it. You want each 1.0 cm length along the scale to correspond to a mass difference of 0.10 kg. What should be the value of the spring constant?

(a) A bathroom scale has a spring that is compressed by 1.50 cm when a 150 kg person stands on the scale. Assuming the spring is described by Hooke's law, find its force constant (in N/m).   ______N/m   (b) How much (in mm) would it be compressed if a 95.0 kg person stands on the scale in an elevator that is accelerating upward at 1.25 m/s²?______mm
