Since the block has no acceleration, So there is only 1 force acting which is frictional force.
so , Fk=-Kx (K is known as spring constant and x is distance covered by the spring)
15=-10000 × x
x=15/(10)^4=15×10^-4 m answer.
3 kg block sides
please help me
I'll only tell the equation, you may please solve it ahead to get the final answer.
By work energy theorem, initial kinetic energy
= Energy dissipated in friction + Elastic potential energy in the spring
Let the compression be x
So, we can write
1/2mv^2 = fx + 1/2kx^2
Just put in all the values, aa everything is given
Hope this helps you !
Solve the quadratic equation to get the final compression.
