An inclined plane makes an angle of \(30^{\circ}\) with the horizontal. A block of mass \(m=2.0\ \text{kg}\) starts from rest at the top of the plane, which is \(5.0\ \text{m}\) long. The coefficient of kinetic friction between the block and the plane is \(\mu_{k}=0.20\). At the bottom of the plane a horizontal spring of force constant \(k=800\ \text{N·m}^{-1}\) is attached to the block. The block compresses the spring by \(x=0.10\ \text{m}\) as it moves down the plane. (i) Determine the speed of the block when the spring is compressed by \(0.10\ \text{m}\).

Answer Options

A. v ≈ 4.1 m/s

C. v ≈ 3.9 m/s
Correct Answer D. v \approx 5.3 m/s
Correct Answer
D
Correct Option:
v \approx 5.3 m/s
