Answer:
oh umm it think its TV=11x*20s
Explanation:
All sources of energy on the planet (excluding nuclear reactions) are ultimately attributable to the sun. 'Fossil fuels' are derived from what once were living organisms, and all sources of food begin with primary producers (plants and algae which utilize photosynthesis).
When ball is about to hit the ground, almost all its potential energy has already converted into kinetic energy. Thus at t=0.9 sec, it has least potential energy.
Answer:
starting position: 3 m
velocity: 3 m/s
Explanation:
at t=0 position= 3 m
velocity: (delta)position/(delta)time
(delta=change in)
velocity= (15-3)/(4-0)
velocity= 12/4
velocity= 3 m/s
