Q1. Cannon at the top of a 147 m high cliff fires at a pirate ship. The cannonball has an initial velocity of 114 m/s at 46° above horizontal. Ignore air resistance. At what angle (positive angle below horizontal) is the cannonball travelling when it hits the water?

Q2. For the polarisers, assume the incident light is linearly polarized, the transmitted intensity (through both polarisers) is 0.15×I0, and the axis of the second polarizer makes an angle θ=41° with the axis of the first polarizer. What is the angle (in degrees) the initial direction of polarization makes with the first polarizer? (Insert the number of degrees without unit.)
