Solve the all parts of following question:

Question: A football tight end travels 19 m straight down the playing field in 2.7 s (in the positive direction). He is then hit and forced 1.5 m straight backwards in 1.6 s. He breaks the tackle and runs straight forward another 19 m in 5.2 s.

Part A: Calculate the tight end's average velocity in the horizontal direction during the first interval, in meters per second.

Part B: Calculate the quarterback's average velocity in the horizontal direction during the second interval, in meters per second.

Part C: Calculate the tight end's average velocity in the horizontal direction during the third interval, in meters per second.

Part D: Calculate the tight end's average velocity in the horizontal direction for the entire motion, in meters per second.

I need help to find the tight end's average velocity in the horizontal direction for the entire motion, in meters per second.
