Resolved. I derived it the second way. Thanks

Do I calculate the impact parameter in terms of vo using equations of orbital motion?

Homework Statement An object from space (like an asteroid) approaches Earth. A collision will occur if the scattering cross-section is less than π*Re2. If the distance of closest approach is much greater than Re, no collision would occur. Find an implicit expression for the cross-section in...

I worked out this problem in the mean time. You are correct! I see that the potential increases with z, which can be determined to be 2Lcosθ. The gravitational potential energy is thus U = 3Lcosθ*mg when we account for g's effect on each mass. The kinetic energy I have determined as well. Then...

Homework Statement Ok, so in this system, there are two point particles of mass M connected by massless levers of length L. The pair of masses pivots about the upper point and rotates about the axis at an angular frequency ω. The lower mass is constrained to slide on the vertical axis. The...

Homework Statement Consider a uniformly charged sphere (an insulating sphere of radius R,) and a spherical Gaussian surface with radius R/2 concentric to the sphere. What is the total flux flowing through the Gaussian surface? Homework Equations Vsphere= (4∏R^3)/3 Asphere= 4∏R^2 Gauss' Law...
