Ahh?
Determine the distance from the base of a cliff 75 meters high to a point in the sea where the shell will strike if the shell is projected horizontally from the top of the cliff with a velocity of 1500m/s?

To determine the distance from the base of the cliff to the point in the sea where the shell will strike, we can use the equation of motion:
h = (1/2)gt^2
Where:
h = height of the cliff (75 meters)
g = acceleration due to gravity (9.8 m/s^2)
t = time taken for the shell to strike the sea
First, we need to find the time taken for the shell to strike the sea. Since the shell is projected horizontally, the vertical component of its velocity is 0. Therefore, the time taken for the shell to strike the sea is the same as the time taken for an object to fall freely from a height of 75 meters:
h = (1/2)gt^2
75 = (1/2)(9.8)t^2
t^2 = 75 / 4.9
t = √(75 / 4.9)
t ≈ 3.87 seconds
Next, we can find the horizontal distance the shell travels using the equation:
d = vt
Where:
d = horizontal distance
v = horizontal velocity (1500 m/s)
t = time taken for the shell to strike the sea (3.87 seconds)
d = 1500 * 3.87
d ≈ 5805 meters
Therefore, the distance from the base of the cliff to the point in the sea where the shell will strike is approximately 5805 meters.
