A 75 Kg skateboarder is riding downhill, exerting 25 N. What is their acceleration?
1 answer:
Answer:
<h3>The answer is 0.33 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
m is the mass
f is the force
a is the acceleration
From the question
f = 25 N
m = 75 kg
We have
We have the final answer as
<h3>0.33 m/s²</h3>Hope this helps you

Answer:
The answer to your question is
4C₇H₁₇ + 45 O₂ ⇒ 28 CO₂ + 34H₂O
Explanation:
Write the equation
C₇H₁₇ + O₂ ⇒ CO₂ + H₂O
Process
1.- Check if the equation is balanced
Reactants Element Products
7 C 1
17 H 2
2 O 3
As the number of reactants and products is different, we conclude that the reaction is unbalanced.
2.- Write a coefficient "7" to CO₂ and a coefficient of 17/2 to H₂O
C₇H₁₇ + O₂ ⇒ 7CO₂ + H₂O
Reactants Element Products
7 C 7
17 H 17
2 O 51/2
3.- Write a coefficient of 45/2 to the O₂, and multiply all the equation by 2.
4C₇H₁₇ + 45 O₂ ⇒ 28 CO₂ + 34H₂O
Reactants Element Products
28 C 28
68 H 68
90 O 90
