Answer:
Rocket Center of Gravity. As a rocket flies through the air, it both translates and rotates. The rotation occurs about a point called the center of gravity. The center of gravity is the average location of the weight of the rocket.
It's dependent on the mass. You can fimd the force needed using the formula F = ma. Where F is force, m is mass of the cart and a is the acceleration (0.9m/s^2). The heavier it is the more force you are going to need. Remember unit of force is N
Is that a question what is that supposed to mean
Answer:
From the concept of energy conservation, Ei=Ef
Explanation:
mgh=1/2mv^2
=> v=
\sqrt{2gh}2gh
=
\sqrt{2 \times 9.8 \times 8.8}2×9.8×8.8
=
\sqrt{172.28}172.28
=13.12m/s.
