Question

a ship of mas 20 million kg travelling at a velocity of 5m/s. calculate its momentum​

Answer 1

Answer:

$10^{8} kgms^{-1}$

Explanation:

The momentum of a body is defined as the product of its mass and its velocity.

Momentum of the ship = Mass of ship × Velocity of ship

                                      = 20,000,000 kg × 5$ms^{-1}$

                                      = 100,000,000 $kgms^{-1}$

                                      = $10^{8} kgms^{-1}$

Answer 2

$\bigstar$ Given

A ship of mas 20 million kg travelling at a velocity of 5 m/s

$\bigstar$ To Find

Momentum

$\bigstar$ Solution

We know that

$\red{\sf \longrightarrow p=mv}$

Here

• p = Momentum
• m = Mass
• v = Velocity

Units

• p = kg m/s
• m = kg
• v = m/s

According to the question

We are asked to find momentum

Therefore

We must find "p"

Given that

A ship of mas 20 million kg travelling at a velocity of 5 m/s

We know that

→ 1 million = 10⁶

Hence

• m = 20 × 10⁶ kg
• v = 5 m/s

Substituting the values

We get

$\sf \longrightarrow p=20 \times 10^{6} \times 5 \ kg \ m/s$

$\sf \longrightarrow p=2 \times 10^{7} \times 5 \ kg \ m/s$

$\sf \longrightarrow p=10 \times 10^{7} \ kg \ m/s$

Therefore

$\pink{\sf \longrightarrow p=\times 10^{8} \ kg \ m/s}$

Hence

$\checkmark$ Momentum = 10⁸ kg m/s
