Answer:
True, because tech is what creates thing like cars and other veicals (i know i spelled it wrong)
hope this helps
Explanation:
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.
