An object is shot 8 m/s horizontally from a 7 m tall cliff. how far away does it land?

R = 9.52 m

Explanation:

When an object is thrown horizontally from a certain height into the air under the effect of the gravitational force, the movement of the projectile is observed. Projectile motion has two component, Horizontal component and vertical component.

Initially, Projectile motion has only horizontal component and vertical component is equal to zero. Gradually vertical component of velocity increases due to the influence of gravity.

As the ball followed the projectile path, and we know that in projectile motion the horizontal component of the velocity remains constant throughout its motion. So there is no acceleration along horizontal path.

Given data :

Initial velocity = = 8 m/s

Height = h = 7 m

Horizontal range = R = ?

According to 2nd equation of motion

h = t + 0.5gt²

7 = 0.5*9.8*t²

t = 1.19 s

Using R = t

R = 8*1.19

R = 9.52 m

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
