answer all the above
the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a string in a horizontal circle at constant speed. Suddenly string breaks. Immediately after the string breaks, the ball will have a horizontal velocity away from the center of the circle have a horizontal velocity that is tangential to the circle. have a horizontal velocity toward the center of the circle. have a horizontal...

The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...

An object moves in a circular path with constant angular speed. Compare the direction of the object's tangential velocity vector to its centripetal acceleration vector. A) Both vectors point in the same direction B) The vectors point in opposite directions C) The vectors are perpendicular D) Impossible. The acceleration is zero. Two objects with masses m1 and m2 are original a distance r apart. The magnitude of the gravitational force between them is F. if BOTH masses are doubled, and...

1.) You whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion. Which of the following is true for this situation? (Select all that apply.) The change in direction of the stone's motion is due to the centripetal force acting on the stone. The direction of the stone's velocity changes as it moves around the circle. The stone is moving with constant velocity. The stone's speed is constant. The magnitude of...
