Answer:
v=30 m/s
Explanation:
h - height
g - acceleration due to gravity=10
t - time
v- velocity
45 = 5t²
t² = 9
t=3 seconds
v=g×t
v=10×3
v=30 m/s
I believe that your current answers are correct, but I also think that you could add:
Water flowing downhill a region.
This is as when water flows downhill a region, it will carry with it an abundant amount of particles which will continue to flow with the water until it finally disperses or ends up in one location.
Answer:
e. Only the rocket's motion from the top of its flight path until just before landing is free-fall.
Explanation:
A free-fall is a fall just under force of gravity. The rocket;s upward motion is result of engine push - even if it was shut down - and rocket free of engine push effect when it reaches it's maximum height after shutting down of engine. Then rockets stops at it's maximum height for a moment and rtuens back as free fall with only force of gravitation pulling it back to ground with acceleration 'g'.
Answer:
120,000seconds
Explanation:
400 minutes x 5= 2000minutes (2000minutes x 60)seconds =120,000seconds.
