Question

a. same time
b. less time
c. more time
d. it cannot be determined

Answer 1

When Anna throws the stone with a higher speed, it will take less time for the stone to hit the ground.

Step-by-step explanation:

When Anna throws the stone with a higher speed horizontally from the top of the cliff, it will take less time for the stone to hit the ground. The time of flight of a projectile depends on its initial velocity and the height from which it is launched. As the stone's speed increases, its horizontal velocity component increases, causing it to cover a greater horizontal distance in the same amount of time. Therefore, the stone will reach the ground faster.
