Question

An object is moving with acceleration of 60m/s^2 and the mass of the object is 5000g .Find the force applied on it.​

Answer 1

♦ Solution :-

Given ,

• Acceleration = 60m/s²
• Mass = 5000g = 5 × 10³ g = 5kg

So , using Newton's first law

• Force (F) = Mass (m) × acceleration (a)

→ Force = 5 × 60

→ Force applied on the body = 300 N

Hence force applied on the body = 300N or 3 × 10² N

Answer 2

Given :-

Acceleration of moving body =

${60m/s}^{2}$

Mass of the object =

$5000g$

To find :-

Force applied on the body

Solution:-

First we have to convert 5000g into kg

As we know ,

To change grams into kilograms we have to multiply by 1000

So

Mass = 5000g × 1000

= 5kg

Now ,

According to Newton's first law of motion

F = ma

Were

• F is the force

• m is the mass

• a is acceleration

⇒ force = 5kg × 60m/s^2

$⇒force = 300 \: kg \: {m/s}^{2}$

$⇒ force = 300 \: newton$

Therefore force applied on the body = 300 Newton
