Answer:
H = start height (v = 0)
h = present height
v = present speed
assuming no friction
total energy = PE + KE
mgH = mgh + .5mv^2
if PE = KE then
mgH = mgh + mgh
h = H/2
potential energy = kinetic energy when object is at half its start height.

Answer:
300 Pascal
Explanation:
Given
weight or force (F) = 6000 N
area (A) = 20 m²
pressure (p) = ?
we know
the force acting normally per unit area is pressure. So
P = F / A
= 6000 / 20
= 300 Pascal
