A football player is standing on the 10 yard line.He runs forward to the 40 yard line and then runs backwards to the 30 yard line.What is the distance that he has traveled and what is his displacement?
A)distance = 20 yards,displacement = 20 yards forward
B)distance = 20 yards,displacement = 30 yards forward
C)distance = 30 yards,displacement = 30 yards forward
D)distance = 40 yards,displacement = 20 yards forward
E)distance = 40 yards,displacement = 40 yards forward

The distance traveled is the total length of the path he has covered, which is the distance from the 10 yard line to the 40 yard line (30 yards), plus the distance from the 40 yard line back to the 30 yard line (10 yards). So, his total distance traveled is 30 + 10 = 40 yards.

The displacement is the straight-line distance from the initial position to the final position. In this case, he started at the 10 yard line and ended at the 30 yard line, which is a displacement of 20 yards forward.
