A 4.68 kg sphere makes a perfectly inelastic collision with a second sphere that is initially at rest. The composite system moves with a speed equal to one fourth the original speed of the 4.68 kg sphere. What is the mass of the second sphere?
Two tugboats pull a disabled super tanker. Each tug exerts constant force of 1.20 multiplied by 106 N, one 19° west of north and the other 19.0° east of north, as they pull the tanker 0.69 km toward the west. What is the total work they do on supe..
Consider an experiment where a subject lands during two conditions from a height of 0.2 m. During the first landing condition, the subject lands 'stiffly' (e.g., very little knee flexion).
