<span>When an object travels in a curved path, there must be a force acting toward the center of the circular trajectory. This force is called "centripetal force", and it cause an acceleration of the object, called "centripetal acceleration". The effect of this acceleration is that the velocity of the object changes in direction: however if the circular motion is uniform, the speed (=the magnitude of the velocity) does not change. In this case, the magnitude of the centripetal force is given by

where m is the mass of the object, v its velocity, and r the radius of the circular path.</span>

where m is the mass of the object, v its velocity, and r the radius of the circular path.</span>
Answer:
a)
b)
Explanation:
a) The displacement of the first object is 22.5 m, so we can use the next equation:
positive acceleration.
b) Using the same equation we can find the second value of the acceleration:
positive acceleration.
