A mass, m1 = 9.04 kg, is in equilibrium while connected to a light spring of constant k = 122 N/m that is fastened to a wall
A second mass, m2 = 7.31 kg, is slowly pushed up against mass m1, compressing the spring by the amount A = 0.220 m The system is then released, and both masses start...
#2 is different from #1... it's.. a small block on a big block.. and the big block has a spring attached to it.. the coefficient of static friction was..0.630.. they want to know what's the maximum amplitude of the oscillation so that the little block doesn't slip..
f= 1.52 Hz
AND for...
it was a picture with a big block on the bottom.. a small block on the top.. with a spring attached to it..
i got the first part of the question.. it was T=2pi sqrt(l/g+a)
but i cannot get the second part of it... with it acclerating horizontally..
1a)A simple pendulum is 4.35 m long. What is the period of simple harmonic motion for this pendulum if it is hanging in an elevator that is accelerating upward at 5.90 m/s2?
b)What is the period of simple harmonic motion for this pendulum if it is placed in a truck that is accelerating...
i did start...
1)
l=4.35 m
a= 5.90 m/s/s
w^2=g/l
w^2=9.80/4.35
w^2= 2.252873563
then i have to find T.. but i don't know what formula to use...
2) w=2(pie)f
w-2(pie)(1.52 Hz)
w= 9.5504
and i don't know what else to do
b)w(friction) should be force of friction*displacement..since the angle is zero
c) work done by gravity is zero because there is no up or down movement of the cart
a) F(applied)=mgcos(theta)
d) w=F(applied)*d
I think. LoL
