Which statement is supported by this scenario? jin is standing still and watching an archer on a horse traveling away from a target. the archer is moving at a speed of 4 m/s and shoots the arrow toward the target with a speed of 17 m/s. for jin, the speed of the arrow is 21 m/s, and for the archer, the speed of the arrow is 4 m/s. for jin, the speed of the arrow is 13 m/s, and for the archer, the speed of the arrow is 17 m/s. for both jin and the archer, the speed of the arrow is 21 m/s. for both jin and the archer, the speed of the arrow is 17

13 for the archer (?)

Explanation:

Since the archer is moving in the same direction as the arrow, the arrow is only going 13 m/s faster than him.

Since Jin is standing still, the arrow would be its actually speed.

This question is a little flawed since technically the arrow is still going 17 m/s for both Jin and the archer.

For Jin, the speed of the arrow is 13 m/s  and for archer speed of the arrow is 17 m/s

Explanation:

The archer shoots the arrow towards the target with the speed of 17 m/s . This speed is with respect to himself. Since he is moving in opposite direction with a speed of 4 m/s that means he must have shoot the arrow with a speed of 13 m/s with respect to ground. This speed when added with his individual speed of 4 m/s makes it 17 m/s with respect to himself. Jin who stands on the ground

sees the speed of arrow as 13 m/s.  

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
