Impact Parameter

(A) the trajetory traced by an incident particle depends on the impact parameter of collision. (R) the impact parameter is the perpendicular distance of the initial velocity vector of the incident particle from the centre of the target nucleus.

A particle of mass m moving with speed u collides elastically with a sphere of radius R and same mass at rest, at an impact parameter d. Find (a) Angle between their final velocities and (b) Magnitude of their final velocities.

A disk A of radious r moving on perfectly smooth surface at a speed v undergoes an elastic collision with an identical stationary disk B. Find the velocity of the disk B after collision if the impact parameter is r//2 as shown in the figure :-

A proton of mass m moving with a speed v_(0) apporoches a stationary proton that is free to move. Assuming impact parameter to be zero., i.e., head-on collision. How close will be incident proton go to other proton ?

For scattering by an inverse square field (such as that produced by a charged nucleus in Rutherford's model), the relation between impact parameter b and the scattering angle theta is given by, b=(Ze^(2)cot theta//2)/(4pi epsilon_(0)((1)/(2)mv^(2))) What is the impact parameter at which the scattering angle is 90^(@) for Z = 79 and initial energy equal to 10MeV ?

A projectile of mass m, charge Z., initial speed v and impact parameter b is scattered by a heavy nucleus of charge Z. Use angular momentum and energy conservation to obtain a formula connecting the minimum distance (s) of the projectile form the nucleus to these parameters. Show that for b = 0, s reduces to the closest distance of approach r_(0) .

Intrinsic rate of natural increase (r) is a very important parameter chosen for assessing impacts of any biotic or abiotic factor on population growth . The value for the Norway rat is _________
