Miguel lara, a rarámuri from copper canyon in mexico runs a 50km race in a time of 5: 05.39 if the race starts at the plaza and continues through the copper canyon arriving back at the starting point in the plaza, what is miguel lara's velocity?

Total path length of race = 50 km

Time taken to complete the race = 5 hour 5 min 39 s

total time is given as = (5 * 60 * 60) + (5 * 60) + 39 s

now we know that speed is given as ratio of distance and time

So the speed for the above motion is 2.73 m/s

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
