un bus de 12 m de longitud pasa por el costado de un poste fijo durante 0,5s ¿Cuánto tardara en cruzar completamente un puente rectilíneo de 132 m de largo?

Rocío strikes a 0.058-kg golf ball with a force of 272n and gives it a velocity of 62.0m/s. how long was ricío club in contact with the ball?

How are calculation for velocity and speed different

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?
