A2 kg block is pushed against a spring (k = 400 n/m), compressing it 0.3 m. when the block is released, it moves along a frictionless, horizontal surface, and then up an incline that has friction (μs = 0.4 and μk = 0.2). how far up the incline does the block slide before coming to rest?

Explanation:

Given values  

Mass (m) = 2kg

K = 400 N/M

Compressing it 0.3 m

The law of conservation of energy:

Energy of the spring deformation.

M mass of the block

x spring deformation

Therefore, if block left the spring (x = 0)

Where, Δl is initial spring deformation

The law of conservation of energy:

Where h is height

Cancel mass "m" each side

Distance along incline equals
