In each of the questions below, hanging a mass m from a spring stretches the spring l meters from its unloaded length. calculate the spring constant k, write the differential equation that governs the motion of the undamped mass-spring system, and find the solution that satisfies the initial conditions specified. units are mks; gravitational constant is 9.8 m/s m-0.2 kg and1.0889meters initial displacement is 0.4 and initial velocity is 0.7 k1.8 kg/s2 0.4 cos(4.24 t)0.4000 sin(4.24t) m 0.3 kg and l-2.4500 meters initial displacement is 0.5 and initial velocity is 0.4 k12 kg/s2 x"+0.5x xt)0.5 cos(0.5 t) 0.4000 sin (0.5 t) m=0.5 kg and l=0.6125 meters initial displacement is 0.9 and initial velocity is 0.9 k=8 x(t) = 0.9 . cos ( 8 t) + 0.4000 . sin ( 8 t)

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
