Valence shell electron pair repulsion (VSEPR) theory is based on the simple idea that electron groups one another through coulombic forces. ... According to VSEPR theory, the repulsions between electron groups on the atom of a molecule determine the geometry of the molecule. The preferred geometry of a molecule is the one in which the electron groups have separation possible. Consequently, for molecules having just one central atom, molecular geometry depends on (a) the of electron groups around the central atom and (b) how many of those electrons groups are

pleaze mark brainliest!

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
