A mass 3m collides head-on with a mass m. Before the collision the masses are moving directly toward one another with the same speed v0. After the collision, the mass 3m is moving in its original direction at speed v0/2. What is the speed v of the mass m after the collision

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?
