Answer:
The velocity is in positive x -direction
The speed is
Explanation:
From the question we are told that
The distance from the house to truck is D = 20 m
The distance traveled back to retrieve wind-blown hat is d = 15
The distance from the wind-blown hat position too the truck is k = 20 m
The total time taken is t = 75 s
Generally when calculating the displacement the Justin's backward movement to collect his wind - blown hat is taken as negative
Generally Justin's displacement is mathematically represented as
=>
Generally the average velocity is mathematically represented as
=>
=>
Generally the distance covered by Justin is mathematically represented as
=>
=>
Generally Justin's average speed over a 75 s period is mathematically represented as
=>
=>
