Assignment Instructions Step 1: Gather materials and necessary information. a) You will collect information about genetically modified foods, including: • A description of what genetically modified foods are • A list of crops that are typically genetically modified • An explanation of why crops are genetically modified • A description of how crops are genetically modified • A list of how genetically modified crops affect society and the environment b) Be sure to keep a list of your references so you can cite them properly later. c) Ask your teacher where you should save your presentation as you work on it. Your teacher

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

we need the questions , i may then you.
