The length of a vertical spring is used to measure force. The newton is defined by assigning 9.80 N to the force exerted by the spring when the standard kilogram is attached. Two types of force considered in this chapter are (1) contact forces, the forces that arise when objects touch; ...

Next, we calculate the length change by finding the original length of the biceps (P2−P3=32+202=20.224) and the deformed length of the same muscle (P2′−P3′=2.99252+(−51.176−19.95)2=71.19). Using Hooke's law, we compute the muscle force as Fmuscle = k× (71.19 − ...

56 When a spring is compressed 2.50*10^(-2)mote from its equilibrium position, the total potential energy stored in the spring is 1.25 × 10-2 joule.Calculate the spring constant of the spring.[Show all work, including the equation and substitution with units.] [2] ...
The displacement from equilibrium of an oscillating weight suspended by a spring and subject to the damping effect of friction is given by y(t)=2^(-t)cos 6t, where y is the displacement (in centimeters) and t is the time (in seconds). Find the displacement when (a) t=0, (b) t...
