Consider an ideal spring that has an unstretched length l0 = 3.3 m. Assume the spring has a constant k = 23 N/m. Suppose the spring is attached to a mass m = 6 kg that lies on a horizontal frictionless surface. The spring-mass system is compressed a distance of x0 = 1.6 m from equilibrium and then released with an initial speed v0 = 4 m/s toward the equilibrium position.

(a) What is the period of oscillation for this system?

(b) What is the position of the block as a function of time. Express your answer in terms of t.

(c) How long will it take for the mass to first return to the equilibrium position?

(d) How long will it take for the spring to first become completely extended?

i got this question

did you got q4 & 5

only number 5 wich is (5/2)*R

the half loop one question and the spring block with friction one?

My bad.


I don´t know the other one

Half loop N= (k*d^2/m-2*g*R)*(m/R)

ocw.mit.edu/courses/physics/8-01t-physics-i-fall-2004/assignments/ps07sol.pdf

check q4 plug in your values, i got different values

i am figuring out the 2nd part

did you got vertical spring one?

did you get the 1st one.. plzz help anyone? plz

does anybody knows the last one(8th question) plzz. hop.

8th

a)(-C_1*r*v_x)/m
b)g-(C_1*r*v_y)/m
c)u*e^(-(C_1*r*t)/m)
d)((m*g)/(C_1*r))-((m*g)/(C_1*r))*e^(-(C_1*r*t)/m)
e)4.6*(m/(C_1*r))
f)0
g)(m*g)/(C_1*r)

did anyone got the vertical spring one?
