a soccer player kicks a soccer ball with a force of 1.8 n. if the mass of the ball is .43 kg. how fast will the ball accelerate?

The acceleration of the ball is 4.18 [m/s^2]

Explanation:

By Newton's second law we can find the acceleration of the ball

Now we have:

The acceleration of the ball is a = 4.186m/s^2

Explanation: By the second Newton's Law we have that:

F = m*a

where F is force, m is mass and a is accleration.

In this case, we have F = 1.8N and m = 0.43kg, so we have to solve the equation:

1.8N = 0.43kg*a

a = 1.8N/0.43kg = 4.186m/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

does anyone know or what?
