Three cars, x, y, and z, begin accelerating from rest at the same time. x is more massive than y, and y is more massive than z. the net accelerating force exerted on each car is identical. after 30 seconds, which car has the most amount of momentum? a) they all have the same amount of momentum. b) car x c) car y d) car z e) cannot be determined based on the known information.

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?
