SEE ATTACHMENT #1 for a diagram of the springs and both arrangements.
Spring A has forceconstant kA= 60 nt/m. Spring B has forceconstant kB= 40 nt/m.
The two springs attached end to end form a series combination with forceconstant Ks.
The two springs attached side by side so that a force applied to the ends stretches bo

Two springs with the same unstretched length, but different forceconstants and are attached to a block with mass on a level, frictionless surface. Calculate the effective forceconstant in each of the three cases depicted in the figure.
a). Express your answer in terms of the variables k1, m, k2
k_eff -c =
b) An object

Prove that when two springs are attached one at the end of the other, the coefficient of the final spring becomes
1 / (1/k1 + 1/k2 ) where k1 and k2 are the coefficient of the two individual springs.
Then consider two systems of springs, one in which a mass m is attached two the end of two springs which a

Question: When an object weighing 50 N is hung from a vertical spring, it stretches 20 cm. Calculate the spring's elastic constant. If the 50 N load were replaced with a 80 N weight, how far would the spring stretch?

An 80kg man jumps from a height of 2.5m onto a platform mounted on springs. The spring compress 0.240 below its initial position and then it rebounds. Platform & spring have negligible mass.
a) What is the spring's forceconstant?
b) What is his speed when the spring is compressed 0.120m?
c) If he gently steps on the plat

You can assume that air resistance and other frictional forces can be ignored in this question

a) Define a datum for the gravitational potential energy of particle P.
b) Write down the gravitational potential energy of particle P at a general point of motion.
c) Write down the kinetic energy of a particl

Which of these collections of subsets are partitions on the set of bit strings of length 8?
a) The set of bit strings that end with 00; the set of bit strings that end with 01; the set of bit strings that end with 10; and the set of bit strings that end with 11.
b) The set of bit strings that end with 111; the set of bit

Two springs are attached in series as shown in Figure 5.42. If the mass of each spring is ignored, show that the effective spring constant k ot the system is defined by I/k = I/k + I/k2.
A mass weighing W pounds stretches a spring 1/2 foot and stretches a different spring 1/4 foot. The two springs are attached, and the mass is

The police chief of the City of Healing Springs has suggested that female patrol officers seek transfers away from high crime areas because he has heard rumors that male officers do not want to have female officers present in dangerous situations and might not support the female officers in the event that physical force is neede
