...velocity between the two colliding objects after impact is zero. In other words, the two objects move with the same velocity Vc (say) after collision . Loss of kinetic energy E = initial kinetic energy (Ei) - final kinetic...
... few electrons are stopped by the target atoms in a single collision . The Bremsstrahlung spectrum is thus a "continuous spectrum...
... electron may need to undergo a number of collisions with the material atoms before it escapes from...material. The is the main reason for the variation in kinetic energy of the photo-electrons. I don...
...electromagnetic radiation. The radiation so emitted is caused by collisions between molecules in the object, which possess thermal kinetic energy energy. By this means, the radiation...
(a) Find the value of m2. m1*v1 = m1*v1' + m2*v2' m2 = m1(v1 - v1')/v2' = m1(v1 - v1')/(4v1/5) = 5m1(v1 - v1')/4v1 (b) Find the relation between v1' and v1. m2 = 5m1(v1/4v1 - v1'/4v1) m2/5m1 = 1/4 - v1'/4v1 v1'/4v1 = 1/4 - m2/5m1 v1'/v1 = 1/16 - m2/20m1 v1' = v1(1/16...
... is just the same as "impact time", which usually used in the case of collision . 2015-08-03 15:52:46 補充： Q:the force should be negatively related...
... most simple approach is to find the speed of car A after collision using conservation of momentum. But in this case, if the two cars are of the same mass, car A should acquire...
... the force acts on the block F = 25 N 2. (a) Fall in height of the person = (30 - 2.75) m = 27.25 m Use equation: v^2 = u^2 + 2as...
