From B, which way does the vector -i cos 35 + j sin 35 point?haha1234 said:
Circular motion is the movement of an object along a circular path. This type of motion occurs when an object travels in a circular path at a constant speed.
Centripetal acceleration is the acceleration that an object experiences when it moves along a circular path. It is always directed towards the center of the circle.
This is because the direction of the centripetal acceleration is always perpendicular to the velocity of the object. In circular motion, the velocity of the object is constantly changing, so the direction of the acceleration also changes. In the i direction, the acceleration is in the opposite direction of the velocity, hence it is negative. In the j direction, the acceleration is in the same direction as the velocity, hence it is positive.
Centripetal acceleration can be calculated using the formula a = v^2/r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path.
Centripetal acceleration is the acceleration towards the center of the circle, while tangential acceleration is the acceleration along the tangent to the circle. Centripetal acceleration causes a change in direction, while tangential acceleration causes a change in speed.
