a-projectile-is-thrown-from-the-edge-of-a-120m-cliff-with-an-initial-velocity-of-140m-s-at-an-pa154

A projectile is thrown from the edge of a $120−m$ cliff with an initial velocity of $140m/s$ at an angle of $45_{∘}$ with the horizontal (figure below). Neglecting air resistance, find: (a) The horizontal distance from the edge to the point where the projectile hits the ground; (h) The greatest elevation above the ground reached by the projectile; (c) When the greatest elevation is reached; (d) The velocity of the projectile just before touching the ground.

Projectile Motion Analysis Given: Initial velocity (v?) = 140 m/s Launch angle (?) = 45 degrees Cliff height (h) = 120 m (a) The horizontal distance from the edge to the point where the projectile hits the ground: The horizontal component of the ...
