Assume that the collision in each scenario is elastic. A graph of the magnitude of the force exerted on Cart Y as a function of time for scenario 1 is shown. During which interval of time does the magnitude of the
momentum of Cart Y change the most?
0.8 to 0.002 s
0.004 s to 0.006 8
0.008 s to 0.010s
The change in momentum is the same for each time interval listed.

Ahollow metal sphere has 6 cm and 11 cm inner and outer radii, respectively. the surface charge density on the inside surface is −100nc/m2. the surface charge density on the exterior surface is:

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
