Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
