Show that the speed with which a projectile leaves the ground is equal to its speed just before it strikes the ground at the end of its journey, assuming the firing level equals the landing level.
ANSWER:
Solution 28P
Step 1 of 2

By neglecting air resistance and taking firing level is equal to level of landing.
Therefore, net vertical displacement of the projectile is zero .
