Their is no document for us to look at , can you add it so i can help you
Answer:
![\boxed{\sf Kinetic \ energy \ (KE) = 85 \ J}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%5Csf%20Kinetic%20%5C%20energy%20%5C%20%28KE%29%20%3D%2085%20%5C%20J%7D%20)
Given:
Mass (m) = 6.8 kg
Speed (v) = 5.0 m/s
To Find:
Kinetic energy (KE)
Explanation:
Formula:
![\boxed{ \bold{\sf KE = \frac{1}{2} m {v}^{2} }}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cbold%7B%5Csf%20KE%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20m%20%7Bv%7D%5E%7B2%7D%20%7D%7D)
Substituting values of m & v in the equation:
![\sf \implies KE = \frac{1}{2} \times 6.8 \times {5}^{2}](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20KE%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%206.8%20%5Ctimes%20%20%7B5%7D%5E%7B2%7D%20)
![\sf \implies KE = \frac{1}{ \cancel{2}} \times \cancel{2} \times 3.4 \times 25](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20KE%20%3D%20%5Cfrac%7B1%7D%7B%20%5Ccancel%7B2%7D%7D%20%20%5Ctimes%20%20%5Ccancel%7B2%7D%20%5Ctimes%203.4%20%5Ctimes%2025%20)
![\sf \implies KE =3.4 \times 25](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20KE%20%3D3.4%20%5Ctimes%2025%20)
![\sf \implies KE = 85 \: J](https://tex.z-dn.net/?f=%20%5Csf%20%5Cimplies%20KE%20%3D%2085%20%5C%3A%20J)
the answer is sex drive, I just took the test
Answer:
a --> true, b --> false, c --> true, d -->false
Explanation:
a) since it stays floating the gravity force and the upqards push is the same
b) if it's balanced the rocket won't move from the ground, the force of the rocket, has to exceed the force of gravity
c) since it's going in a diretion the force of gravity is exceeding the force pushing it up
d) since that are speeding up at a rate, meaning growing, the force is unbalanced.
Are there any options??
I would have to say metal of course but without options I can't assume anything
