Las Vegas Raiders' running back Josh Jacobs is 72 inches tall and has mass of 100 kg. Los
Angeles Rams' defensive tackle Aaron Donald is also 72 inches tall but has a mass of 130
kg. Josh runs the ball East, towards the goal line, quickly traveling 50 yards in
5.5 seconds. Josh then accelerates towards the goal line at 9 m/s2. Aaron accelerates
West, the exact opposite direction, towards Josh at 6.5 m/s2. They both meet with an
explosive collision at the 1 yard line.
In a paragraph, address the following questions. Calculate numerical answers to the
nearest hundredth and correct units must be included.
1. What is Josh Jacobs' speed?
II. What is Josh Jacobs' velocity?
III. How much force does Josh Jacobs create?
IV. How much force does Aaron Donald create?
V. By calculating the net force, does Josh Jacobs score the touchdown.
Explain why or why not?
Answer:
Josh is running at a speed of 9.09 yards per second.
Josh's velocity is 9.09 East.
Josh's force is 900 N.
Aaron Donald's force is 845 N.
Yes Josh scores the touchdown because he is faster and has more mass than Donald.
Explanation:
Josh scores the touchdown as he is heavier and faster than Donald.
Formulas are:
Force= mass x acceleration
Speed= distance divided by time.
Velocity= distance divided by time.

Answer:
Even though plants are rooted in the ground, they still move, exert force, and do work.
Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.
When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.
When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

In if the reaction below 49 grams of Fe3O4 produces a 78.25% yield of Fe. How many grams are produced? Fe3O4 + 4H2 = 3Fe + 4H2O
Imagine the = is an arrow
Fe produced : 27.53 g
Further explanationReaction
Fe₃O₄ + 4H₂ = 3Fe + 4H₂O
mol Fe₃O₄ (MW=233.55 g/mol) :
[tex]\tt \dfrac{49}{233.55 g/mol}=0.21[/tex]
mol ratio Fe₃O₄ : Fe = 1 : 3, so mol Fe :
[tex]\tt 3\times 0.21=0.63~g/mol[/tex]
mass Fe(Ar=55,845 g/mol)
[tex]\tt 0.63\times 55,845=35.18~g[/tex]
grams produced :
[tex]\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\actual=\%yield\times theoretical\\\\actual=78.25\%\times 35.18\\\\actual=27.53~g[/tex]
