A cannon is fired horizontally at 243 m/s off of a 62 meter tall, shear vertical cliff. How many seconds will have elapsed before the cannon ball strikes the ground?

Horizontal component of ball, u = 0 m/s.

Height from which it thrown, h = 62 m.

By equation of motion :

Putting all given equation, we get :

Therefore, time taken is 3.52 s.

Hence, this is the required solution.

i believe the answer is a

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
