Lions can run at speeds up to approximately 80.0 km/h. A hungry 105 kg lion running northward at top speed attacks and holds onto a 35.0 kg Thomson's gazelle running eastward at 77.0 km/h. Find the final speed up of the lion-gazelle system just after the lion attacks. Uf = m/s Find the angle 0 between the final velocity of the lion-gazelle system and the East axis, with positive angles measured counterclockwise from the East axis. 0 =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 0.0207 kg, 0.0101 kg, 0.0227 kg, and 0.0115 kg. At this very instant, the x- and y-components of the mice's velocities are, respectively, (0.521 m/s, -0.479 m/s), (-0.849 m/s, -0.835 m/s), (0.191 m/s, 0.805 m/s), and (-0.309 m/s, 0.745 m/s). Calculate the x- and y-components of Bryce's mice's total momentum, px and py. Px kg-m/s Py= kg-m/sA T53 kg linebacker (X) is running at 119 ms; directly toward the sideline of a football eld. He tackles a 90.4 kg running back (CI) moving at 9.05 mfs straight toward the goal line. perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go outofhounds at an angle d: relative to the sideline, as shown in the diagrams.
