Answer:
It acts at a right angle to the object's motion and causes the object to constantly change direction
Explanation:
When an object moves in a circular path, the force acting on it is called the centripetal force. The magnitude of this force is given by :
Here,
m is the mass of object
v is the velocity of object
r is the radius of circular path
When an object moves in a circular path, its direction keeps on changing while its speed remains the same. The centripetal force acts at an angle of 90 degrees to the motion of an object.
So, the correct option is (a). "It acts at a right angle to the object's motion and causes the object to constantly change direction".

Answer:
The kinetic energy of the baseball is 306.25 joules.
Explanation:
SInce the baseball can be considered a particle, that is, that effects from geometry can be neglected, the kinetic energy (), in joules, is entirely translational, whose formula is:
(1)
Where:
- Mass, in kilograms.
- Speed, in meters per second.
If we know that and
, then the kinetic energy of the baseball thrown by the player is:
The kinetic energy of the baseball is 306.25 joules.
