Curling Rock Hits a Spring

A curler is practicing for the national curling championships to get the perfect momentum and strength on the push of a curling rock. The rock has a mass of \(m = {{ params.m }} \ \rm{kg}\) and hits a spring target at the end. Find the work done by the spring, and the speed of the rock when it reached the spring, if the spring constant is \(k = {{ params.k }} \ \rm{N/m}\) and the spring compresses \(d = {{ params.d }} \ \rm{cm}\). The coefficient of friction on rough ice sheet is \(\mu = {{ params.mu }}\).

Part 1

What is the work done by the spring?

Answer Section

Please enter in a numeric value in J.

Part 2

With what velocity does the rock impact the spring?

Answer Section

Please enter in a numeric value in \(\ \rm{m/s^2}\).
