Homework Statement
A car towing a 92 kg trailor with a spring between the car and the trailor. the accelertion of the car is .3. the spring constant is 2300
how far is the spring stretched
Homework Equations
Fs=kx
The Attempt at a Solution
Fs=kx
ma=kx
(92)(.3)=2300x
x=.012m...
there is no acceleration so the net forces are equal to 0
the other forces would be the force is is being pushed toward the spring and maybe something to do with the friction force
Homework Statement
A 30.0 kg block is resting on a flat horizontal table. On top of this block is resting a 15.0 kg block, to which a horizontal spring is attached. The spring constant of the spring is 325 N/m. The coefficient of kinetic friction between the lower block and the table is...
do u ahve to make the force perpendicular to the point f contact so one equation would be Frcos45=t
then i don't knwo where to go i am trying to make stuff up to trigger my mind
I have a quiz tommorrow and i am reviewing the harder problems and i can't get started on this one
A bicycle Wheel is resting against a small step whose height is h=0.120 m. The weight and radius of the whell are W=25.0N and r=0.340 m. A horizontal force F is applied to the axle of the...
