A 34.2 kg block slides with a velocity of 10.22 m/s to the right on a frictionless surface (as shown in the
figure above). The block slides up a slope to a height of 3.00 m and then slides across a 2.50 m long
rough surface with a coefficient of kinetic friction equal to 0.325. The block continues to travel to the
right and bumps into a massless spring with a spring constant (k) equal to 2320 N/m.
a) How much does the spring get compressed by the block with respect to its equilibrium length?
Please answer with a positive number in units of metres, with 3 sig figs. Start with conservation
of energy: E, = E; + WNC , and show all steps.
b) What is the potential energy stored by the spring when the mass comes to a stop? Please show
the symbolic equation and then "plug in the numbers" to give a numerical answer in units of
joules with 3 sig figs.
c) What happens to the potential energy stored in the spring after the block stops moving to the
right? [no calculation required]
