Question

A track runner, with a mass of 73.0 kg, slides on the ground after tripping and falling. At the start of the slide, the runner moves at a speed of 3.80 m/s before coming to rest. The coefficient of friction between the runner and the ground is 0.700. (a) Find the change in mechanical energy of the runner (in J) from the start of the slide to when she comes to rest. (b) How far (in m) does the runner slide

Step 1

Given: Initial velocity, \(v_i = 3.80 \, \text{m/s}\) Final velocity, \(v_f = 0 \, \text{m/s}\) Mass of the runner, \(m = 73.0 \, \text{kg}\) The change in kinetic energy is given by: \[\Delta KE = KE_{f} - KE_{i}\] \[KE_{f} = 0 \, \text{J} \quad \text{(final Show more…
