A pebble with mass m is thrown straight up with an initial s

A pebble with mass m is thrown straight up with an initial speed v₀ so that its maximum altitude is h. Where will it land? Discuss the difference between this case and one discussed in class of the pebble dropped from a height h.

Solution

time taken by the pebble from maximum height to reach the ground is

            t=   sqrt ( 2 h / g )

Horizontal distance covered by the pebble is

       R = v_x t

            =v_o   (sqrt ( 2 h / g ) )
