Question

Use Newton’s second law (Fnet = ma) to answer each question. SHOW ALL YOUR WORK, including the units! 1N = 1 kg m/s2

A space pod with a mass of 20.0 kg has a force of 5.0 Newtons applied to it. What is the resulting acceleration of the object?

Answer 1

Given :

• Mass of space pod (m) = 20.0 kg or 20 kg
• Force (F) = 5.0 N

To find :

• Acceleration (a)

According to the question,

In this question we will use the formula of F = ma,

→ F = ma

Where,

• F stands for Force
• a stands for Acceleration
• m stands for Mass

→ Substituting the values

→ 5 = 20 × a

→ 5 ÷ 20 = a

→ 0.25 = a

.°. The acceleration is 0.25 m/s²...

☛ Putting the given values ☚

➞ 5 = 20 × a

➞ 5/20 = a

➞ 1/4 = a

➞ 0.25 = a

∴ Tʜᴇ ᴀᴄᴄᴇʟᴇʀᴀᴛɪᴏɴ ɪs 0.25 m/s²
