Spring on an Incline#

A small 3 kg block is accelerated from rest on a flat surface by a compressed spring (\(k\) = 665 \(N/m\)) along a frictionless, horizontal surface. The block leaves the spring at the spring’s equilibrium position (\(x\) = 0) and travels on an incline (\(\theta\) = 25\(^{\circ}\)) with a coefficient of kinetic friction \(\mu_k\) = 0.25. The block moves a horizontal distance \(D\) = 7 m before coming to a stop.

Pictured is a block being pushed towards a ramp by a compressed string.
