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.
1. greater than, equal to, less than  The speed of ball 1 at point G is _______ the speed of ball 2 at point B.
2. greater than, equal to, less than 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 F.
3. greater than, equal to, less than  The magnitude of the vertical component of the velocity of ball 1 at point E is _______ the magnitude of the vertical component of the velocity of ball 2 at point A.
4. greater than, equal to, less than The magnitude of the vertical component of the velocity of ball 1 at point H is _______ the magnitude of the vertical component of the velocity of ball 2 at point F.
5. greater than, equal to, less than  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 A.

Explanation / Answer

1) both will have the same y component but 2 will have an x component

so less than

2. ball 1 horizontal = 0

ball 2 is >0

so less than

3) both are falling the same in the y

so equal to

4) ball 2 fell further at F so it is greater

so elss than

5) horizontal component doesnt change

so equal to
