Final answer:
The question involves calculating outcomes such as time to impact and impact velocity for objects in free fall and projectile motion, relevant to high school level Physics.
Step-by-step explanation:
The question seems to be related to free fall and projectile motion, both of which are important concepts in high school level Physics. In such problems, important equations of motion are utilized to determine various outcomes like time elapsed before hitting the ground, the velocity upon impact, and the distances covered.
For instance, when a ball is dropped from a height, and air resistance is ignored, the time it takes to fall can be calculated using the equation of motion s = ut + 0.5at², where s is the displacement, u is the initial velocity (0 m/s in case of just being dropped), a is the acceleration due to gravity (approximately 9.81 m/s²), and t is the time. These problems usually do not require initial horizontal velocities as there are none in a drop. However, for a horizontally thrown ball, the initial horizontal velocity is also considered, alongside the effects of gravity acting on the object, to determine the trajectory.
