Aheavy bus and a light car both start at rest at the starting line of a long race track. at t = 0, the race begins. both vehicles have the same constant net force during the race. after 10 seconds, the car passes the finish line.
which vehicle crosses the finish line with more kinetic energy? explain your reasoning. ["light car", "heavy bus", "same", "cannot be determined"]
which vehicle crosses the finish line with more momentum? explain your reasoning. ["light car", "heavy bus", "same", "cannot be determined"]
at time t = 5 seconds (while the race is still happening), which vehicle has more kinetic energy? explain. ["light car", "heavy bus", "same", "cannot be determined"]
at time t = 5 seconds (while the race is still happening), which vehicle has more momentum? explain. ["light car", "heavy bus", "same", "cannot be determined"]

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
