NEED TO SHOW ALL WORK) For each of the equations given below, use the triangle method to solve for the
Lelechka [254]

Answer:

1) a=\dfrac{F}{m}

2) m=\dfrac{p}{v}

Step-by-step explanation:

1) The given equation is

F=ma

We need to solve this for a.

In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

F=ma

a=\dfrac{F}{m}

m=\dfrac{F}{a}

Therefore, the required answer is a=\dfrac{F}{m}.

2) The given equation is

p=mv

We need to solve this for m.

In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

p=mv

m=\dfrac{p}{v}

v=\dfrac{p}{m}

Therefore, the required answer is m=\dfrac{p}{v}.
