We can solve these equations by using substitution method where you substitute one equation to the other and solve for the value of the other variable. We do as follows:

y = 2x^2
y = –3x −1

2x^2 = –3x −1
2x^2 +3x +1 = 0

x1= -0.5
x2 = -1
y1 = 0.5
y2 = 2

What is the mass of an object if it takes a net force of 32 N to accelerate
Sonbull [250]

We will find the answer using the second law of motion i.e. Force is equal to the product of mass and acceleration.

\sf \: F=ma

Where,

  • F is force
  • M is mass
  • A is acceleration

In our case,

  • F = 32 N
  • A = 0.88m/s
  • M = ?

Let's solve for M ~

\tt \: 32 = m \times 0.88

\tt \: 32 = 0.88m

\tt \: 0.88m = 32

\tt \: m = 36.36

<em>Thus, The mass of object is 36.36 </em><em>grams</em><em>.</em><em>.</em><em>.</em><em>~</em>
