Two projectiles launched with the same initial speed but at different launch angles 30° and 60° land at the same spot. Ignore air resistance. Use the following choices to answer the following two questions. a) Projectile launched at 30° b) Projectile launched at 60° c) They are equal d) not enough information given e) Which has the larger horizontal velocity component vx? Which has a longer time of flight At? f)

Use the exact values you enter to make later calculations.A ray of light strikes a flat, 2.00-cm-thick block of glass (n = 1.96) at an angle of ? = 32.4° with respect to the normal (see figure below). A light ray incident on a glass block of thickness 2.00 cm is shown. The ray travels down and to the right and is incident to the top of the block at an angle ? to the normal of the surface. The ray inside the block moves down and to the right but at a steeper slope than the incident ray. It is incident on the bottom surface of the block and exits moving down and to the right, in the same direction as the incident ray. A dashed line extends from the original path of the ray down in the block and is shown to be a distance d from the ray that exits the glass block. (a) Find the angle of refraction at the top surface and the angle of incidence at the bottom surface. °(b) Find the refracted angle at the bottom surface. °(c) Find the lateral distance d by which the light beam is shifted. cm(d)…
