Question

a canon is firing horizontally from the high wall of a castle located in the midst of a flat plain. if i drop a canon ball from the wall where the canon is located, it it takes 3 sec to hit the ground. what do i need to know to find how far away from the wall the canon balls will land when fired from the canon? the exit velocity from the canon, only. no further information is needed. the height of the wall, only.

Answer 1

D=44.13, Horizontal velocity is unimportant. The time it takes the cannon ball to fall to the ground is the key to determining the height of the cliff. where  that cannon is present.

The speed of any projectile travelling along a Horizontal velocity is known as the horizontal velocity. When a particle or object is launched into the air at an angle other than 90 degrees, it moves along the trajectory path and changes the shape of the curve to a parabolic one.

the speed at which velocity changes over time. Due to its magnitude and direction, acceleration is a vector quantity. The first derivative of velocity with respect to time or the second derivative of position with respect to time are further examples. This is called acceleration.

Distance to the ground is d = 1/2gt^2,

where g is the acceleration rate of gravity (9.80665 m/s^2)

and t = 3 secs.

d = .5×9.80665×9 = 44.13 m.
