Question

what will be mass of body of force 7.10N on it, produces an acceleration of 2m/s2​

Answer 1

$\Large\underline{\textsf{\textbf{\purple{ \mapsto Required\:Answer:}}}}$

Given that the force of 7.10 Newton produces a acceleration of 2m/s² . Let us take the mass be m . So we know that force is :-

★ Force = mass × acceleration ★

⇝ Force = mass × acclⁿ .

⇝ 7.10 N = m × 2m/s² .

⇝ m = 7.10N / 2m/s².

⇝ m = 3.55 kg .

Hence the mass is 3.55 kg .

★ More Formulae :-

• Force = mass × acclⁿ
• Work =| F | |s | cosθ

★ Equations of Motion :-

• v = u + at .
• s = ut + ½at².
• 2as = v² - u²

where v is final Velocity , u is Initial velocity , s is distance travelled , t is time taken and a is acceleration .

Answer 2

Solution :-

Given ,

• Force = 7.10N
• Acceleration of the body = 2m/s²

We need to find ,

• Mass of the body

Using finding the mass using Newton's first law

• F = m × a

By simplifying

• m = F/a

Where ,

• F → force = 7.10 N
• m → mass = ?
• a → acceleration = 2 m/s²

Substituting we have ,

⇒ m = 7.10/2

⇒ Mass of body = 3.55 kg

Hence , mass of body = 3.55 kg
