Question

three identical balls are thrown from the top of a cliff and sometime later land at the base of the Cliff. Ball A is thrown upward with velocity Va, Ball B is thrown downward with velocity Vb and ball C is thrown at speed Vc at an angle of 45degree above the horizontal. Comparing the speeds Va, Vb and Vc with which balls hit the ground at the base of the cliff and ignoring air resistance, relate the three speeds.

Answer 1

All the three velocities will be same. However, the time taken by each ball will be different.

Answer 2

Answer:

The correct answer is velocity of three balls.

Explanation:

Let velocity be

$V_{1} = V_{2} = V_{3}$ for all the three balls.

Now, we can understand from the following statement that;

The first and 1/3 balls accelerate after they're thrown, while the second one ball to start with slows down, however then hastens after accomplishing its peak.

The paths of all the 3 balls are parabolas, and the balls take distinct time periods to attain the floor due to the fact they have got distinct preliminary velocities.

All 3 balls, however, have the identical velocity in the meanwhile they hit the floor due to the fact all begin with the identical kinetic power and due to the fact the ball-earth device undergoes the Identical kinetic power and due to the fact the ball-earth device undergoes the identical extrude in gravitational capability power in all 3 cases.
