Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

In a game of basketball, a forward makes a bounce pass to the center. the ball is thrown with an initial speed of 4.3 m/s at an angle of 15° below the horizontal. it is released 0.80 m above the floor. what horizontal distance does the ball cover before bouncing?

The [email protected] wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
