Alonzo sprints for 500 meters along a straight track during a race. after crossing the finish line, he to walks back along the track for 50 meters to cool down. what is alonzo's displacement? 450 meters, straight ahead 500 meters, straight ahead 550 meters, straight ahead

450 meters straight ahead

Explanation:

As we know that displacement is the total vector displacement of the object from initial point to final point

As here the Alonzo moves in a straight line during the finish line which is at distance of 500 m

so initial displacement is given as

now for cool down he again moves back 50 meter along the same track in backward direction

so it is given as

so we can say that total displacement will be

straight ahead
