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...

Force of weight on the lower block FT=Force of the Spring

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

goign to set right positive, oppsite of force T Force on the spring=kx Force of weight= mg Force of kinetic energy= uma i think that's all i know

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...

can u maybe help me with an equation i am confused on what u are saying

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 tomorrow 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...
