Question

If the mass of a moving object, is 50g, what force will
be required to speed up the object at a rate
of
2ms -2​

Answer 1

Given:-

• Mass of an object (m) = 50g

• Acceleration (a) = 2m/s²

To Find:-

• Force required to speed up (F)

Solution:-

Firstly we convert the mass of an object in kg

1 kg = 1000g

∴ 50g = 50/1000 = 0.05Kg

As we know that Force is the product of mass and acceleration

→ F = m×a

Substitute the value we get

→ F = 0.05×2

→ F = 0.1 N

∴ The Force required to speed up is 0.1Newton

Additional Information !!

✧ Product of mass and acceleration is called force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR

A push or pull of an object is called force.

✧ SI unit of Force is Newton.

✧ It is denoted by N.

✧ Force is vector Quantity i.e., both Magnitude and direction.

✧ Mathematical term

⟹ Force = Mass×Acceleration

Answer 2

Given :

• Mass (m) = 50 g
• Acceleration (a) = 2 m/s²

To find :

• The force (F)

According to the question,

At first we will change g into kg

$\sf{ \frac{5 \cancel0}{100 \cancel0} } = 0.05 \: kg \orange \bigstar$

Now according to the formula,

$\star \boxed{ \sf \red{F = ma}}$

We will put the values,

$\sf { \: \: : \implies0.05 \times 2}$

$\sf { \: \: : \implies \frac{5}{ \cancel{100} {}^{ \: \: 50} } \times \cancel 2}$

$\sf{ \: \: : \implies \cancel\frac{5}{50} } = 0.1$

$\sf{ \: \: : \implies 0.1\:N}\orange\bigstar$

.°. The force is 0.1 N...
