In order to attain orbit around earth, the ATLAS-V rocket must accelerate up to a
IrinaK [193]
A) average acceleration = final velocity - initial velocity / time

= 7700 - 0 / 11

= 700ms^-2


B) force = mass x acceleration

= (3.05 x 105) x 700

= 320.25 x 700

= 224,175N

. A rock is dropped from a height of 4 m. How fast is it going when it hits the ground? The rock has a mass of 2 kg. (Hint: MEi
Bas_tet [7]

Hello!

When the rock is dropped, it only contains Gravitational Potential Energy, and when it hits the ground, it contains Kinetic Energy.

So:

PE = KE
\large\boxed{mgh = \frac{1}{2}mv^2}

We can rearrange to solve for velocity. Cancel out mass and solve.


gh = \frac{1}{2}v^2\\\\2gh = v^2\\\\v = \sqrt{2gh}

Plug in the givens:


v = \sqrt{2(9.8)(4)} = \boxed{8.85 \frac{m}{s}}
