Light traveling through the air strikes the surface of the four materials below. which material reflects light but does not refract it?

a) diamond
b) water droplets
c) prism
d) metal spoon

truck y has a greater velocity than truck x.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

answer; how far out of place which the object finished relative to the starting location;
