Astudent throws a baseball horizontally at 25 meters per second from a cliff 45 meters above the level ground. approximately how far from the base of the cliff does the ball hit the ground? [neglect air resistance.]

A baseball is thrown horizontally at 25 m/s from a cliff 45 m above the level ground and it hits the ground 75 m from the base of the cliff.

First, we will calculate the time the baseball is in the air by analyzing the vertical movement.

This is a uniformly accelerated motion, where the initial vertical velocity (u) is 0, the displacement (s) is 45 m and the acceleration is that of gravity (a = 9.8 m/s²).

We can calculate the time (t) in the air using the following kinematic equation.

Horizontally, it travels for 3.0 s at a speed of 25 m/s. The horizontal distance traveled is:

A baseball is thrown horizontally at 25 m/s from a cliff 45 m above the level ground and it hits the ground 75 m from the base of the cliff.

Neglecting air resistance, the distance from the base of the cliff where the baseball hit the ground is approximately 75.75m.

Given the data in the question;

First, we determine the time taken. Using the second equation of motion:

Where s is the height of the cliff, u is initial velocity, t is time taken, a is acceleration due to gravity( )

We substitute in our values

Now, to get the horizontal distance, we simply multiply the velocity of the baseball and time taken

Horizontal distance =

Horizontal distance =

Therefore, neglecting air resistance, the distance from the base of the cliff where the baseball hit the ground is approximately 75.75m.
