1. Acceleration is the rate of change of velocity with respect to time
u = 10m
v = 40m
t = 3s
Substituting the value -
2. In the circular motion the acceleration is constant acting because of change of direction is every second. So the circular motion is the accelerated motion.
Hence, the boy is moving in accelerated motion.
ADDITIONAL INFORMATION -
Rest - An object is at rest if it's position does not change with passage of time w.r.t to observer.
Motion - An object is at motion if it's position change with passage of time w.r.t to observer.

Important formulas -
v = u + at
v² = u² + 2as
s = ut + ½at²
Snth = u + (2n - 1)a/2
