An airplane needs to reach a forward velocity of 56.4 m/s to take off. On a 2000 meter runway, what is the minimum uniform acceleration necessary for the plane to take flight if it starts from rest? SHOW WORK OR GET REPORTED!! What is the displacement of the airplane?

What is the initial velocity of the airplane?

What is the final velocity of the airplane?

Write the equation you will use to solve the problem.

What was your acceleration?
1.0 m/s^2
0.95 m/s^2
0.87 m/s^2
0.80 m/s^2

What was your acceleration?

1.0 m/s^2

0.95 m/s^2✔

0.87 m/s^2

0.80 m/s^2

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
