Question

A body of mass 2kg at rest .A force of 20 N acts on the body calculate the acceleration produced in the body​

Answer 1

Aɴsᴡᴇʀ:

• The required acceleration produced in the body = 10m/s²

Gɪᴠᴇɴ:

• A body of mass 2kg at rest. A force of 20 N acts on the body.

Nᴇᴇᴅ ᴛᴏ ғɪɴᴅ:

• The required acceleration produced in the body = ?

Solution:

Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ:

• Force = Mass × Acceleration

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs:

➥ 20 = 2 × acceleration

➥ Acceleration = 20/2

➥ Acceleration = 10

Tʜᴇʀᴇғᴏʀᴇ:

• The required acceleration produced in the body = 10m/s²

Answer 2

Given:

• Mass of body, m = 2 kg
• Force acting on body, F = 20 N
• Initially body was at rest

To find:

• Acceleration produced in the body, a =?

Formula required:

• Expression for Newton's second law of motion

      F = m a

[ Where F is force exerted, m is mass and a is acceleration produced ]

Calculation:

Using Expression for Newton's second law of motion

→ F = m a

→ 20 = ( 2 ) . a

→ a = 20 / 2

→ a = 10 m/s²

Therefore,

• Acceleration produced in the body would be 10 m/s².
