Answer #1

Let the cannon is fired with an initial speed v0. The maximum height reached by the projectile is given by

Horizontal distance traveled by the cannon in the given time

Whereas the vertical speed is zero at the maximum height

is the time taken by the cannon to reach maximum height.

Now the ratio

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...
