Question

Two identical balls A and B are dropped off the edge of a table at the same moment. Ball B has no initial velocity, while Bal A has an initial velocity vAo in the horizontal direction as indicated. Which ball hits the floor first? O Ball A O Ball B O Both balls hit the floor at the same time ??- Submit Answer Tries 0/2 Which ball has the higher momentum just before it hits the ground? O Ball A O Ball B O Both balls have the same momentum Submit Answer Tries 0/2 Which ball has the higher kinetic energy just before it hits the ground? O Ball A O Ball B Both balls have the same kinetic energy Submit Answer Tries 0/2 The table has a height of 1.15 m, and the initial speed of ball A is vAo 2.5 m/s. What is ball A's speed just before it hits the floor? (in m/s) A: 3.1B: 3.9 c: 5.4 D: 6.1 Submit Answer Tries 0/1 At what distance from the table's edge l ball A hit the floor? (in m) A: 1.0 B: 1.2 Oc: 1.4 D: 1.7 Submit Answer Tries 0/1

Explanation / Answer

(a) Both balls hit the floor at the same time.

(b) Ball A has higher momentum as it has a velocity component in the horizontal direction as well.

(c)  Ball A has higher kinetic energy as it has a velocity component in the horizontal direction as well.
