Question

An object is thrown horizontally from the top of a tower with velocity 19.6 m/s.What time elapses before the horizontal and vertical velocities become equal❔​

Answer 1

Answer:

the answer is 9.8 m/s

Explanation:

The horizontal velocity is 9.8 m/s and that is not going to change as there are no components of force in horizontal direction.

The acceleration due to gravity ( which is vertically downwards ) is 9.8 m/s^2 which means the object will gain 9.8 m/s of velocity every second.

Thus, in 1 second, vertical velocity will become 9.8 m/s which is equal to the horizontal velocity.
