Question

Steel ball 1 is released from rest at the same time steel ball 2 is given a horizontal kick. The dots represent the locations of the two balls at t=0,1,2,3 and 4 s. The balls continue to fall after t=4 s. Evaluate each of the following statements with either greater than, less than, or equal to.

1.The magnitude of the horizontal component of the velocity of ball 1 at point C is _______ the magnitude of the horizontal component of the velocity of ball 2 at point E.
2.The magnitude of the vertical component of the velocity of ball 1 at point F is _______ the magnitude of the vertical component of the velocity of ball 2 at point G.
3.The speed of ball 2 at point A is _______ the speed of ball 1 at point B.
4.The magnitude of the vertical component of the velocity of ball 1 at point C is _______ the magnitude of the vertical component of the velocity of ball 2 at point E.
5.The magnitude of the horizontal component of the velocity of ball 2 at point D is _______ the magnitude of the horizontal component of the velocity of ball 2 at point E

Explanation / Answer

Steel ball 1 is released from rest at the same time steel ball 2 is given a horizontal kick.

To evaluate each of the following statements are :

1. The magnitude of the horizontal component of the velocity of ball 1 at point C is Less than the magnitude of the horizontal component of the velocity of ball 2 at point E.

2. The magnitude of the vertical component of the velocity of ball 1 at point F is Less than the magnitude of the vertical component of the velocity of ball 2 at point G.

3. The speed of ball 2 at point A is Greater than the speed of ball 1 at point B.

4. The magnitude of the vertical component of the velocity of ball 1 at point C is Equal to the magnitude of the vertical component of the velocity of ball 2 at point E.

5. The magnitude of the horizontal component of the velocity of ball 2 at point D is Equal to the magnitude of the horizontal component of the velocity of ball 2 at point E.
