how
pls tell how
a) 42m (diametre)
In 5s he complete half round so from one end to another the displacement is diametre as displacement is the shortest distance between 2 points.
b) 0m (as he comes back)
He comes back to the starting point.the displacement is diametre as displacement is the shortest distance between 2 points.
c) 66m (half circumference)
He covers half the circle in 5s and distance is the total path moved.
