Hi
A block ( 0.5 kg ) is attached to a spring ( k = 40N/m ) on a frictionless table..
The spring is 0.6 meter long unstretched ..
A constant force (20 N ) is applied horisontaly causing the spring to stretch
1) question : what is the speed/velocity of the box after 0.25 meter ?
can anyone help me with this ?
I understand that the box accelerates according to F=ma in the beginning , but when the spring starts to exert force in the other direction , that's when I am loosing it
