Question

A body of mass 5 kg accelerates from 12 m/s to 20 m/s in 4 seconds due to the application of a force on it. Calculate the magnitude of this force (in N).​

Answer 1

Aɴsᴡᴇʀ:

• The magnitude of this force in N = 10 N

Gɪᴠᴇɴ:

• A body of mass 5 kg accelerates from 12 m/s to 20 m/s in 4 seconds due to the application of a force on it.

Nᴇᴇᴅ ᴛᴏ ғɪɴᴅ:

• The magnitude of this force in N = ?

Solution:

Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ:

• Force = Mass × (v - u/t)

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs:

➦ Force = 5 × (20 - 12/4)

➦ Force = 5 × (8/4)

➦ Force = 5 × 2

➦ Force = 10 N

Tʜᴇʀᴇғᴏʀᴇ:

• The magnitude of this force in N = 10 N

Answer 2

Step-by-step explanation:

Formula used here:

• Force = Mass × (v - u/t)

Putting the values:

➦ Force = 5 × (20 - 12/4)

➦ Force = 5 × (8/4)

➦ Force = 5 × 2

➦ Force = 10 N

Therefore:

• The magnitude of this force in N = 10 N
