The centripetal acceleration is
Explanation:
The centripetal acceleration for an object in circular motion is given by
where
v is the linear speed
r is the radius of the circle
The body in the problem cover half of revolution in
t = 10 s
And the corresponding linear distance covered is
L = 10 m
which corresponds to half of the circumference, so
From this equation we find the radius of the circle:
[m]
While the linear speed is:
Therefore, the centripetal acceleration is
