Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time, when they're not sleeping or eating, joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 0.0137 kg, 0.0245 kg, 0.0155 kg, and 0.0213 kg. At this very instant, the x- and y-components of the mice's velocities are, respectively, (0.769 m/s, -0.393 m/s), (-0.919 m/s, -0.889 m/s), (0.797 m/s, 0.219 m/s), and (-0.793 m/s, 0.317 m/s). Calculate the x- and y-components of Bryce's mice's total momentum, p, and py. kg-m/s Pr = kg-m/s A 0.350 kg lump of clay is dropped from a height of 1.15 m onto the floor. It sticks to the floor and does not bounce. What is the magnitude of the impulse J imparted to the clay by the floor during the impact? Assume that the acceleration due to gravity is g = 9.81 m/s. max J = kg · m/s The force exerted by the floor on the clay is plotted as a function of time in the figure. What must have been the maximum force Fmax exerted by the floor on the clay? Fmax 7.5 ms Time (ms) Force (N)
