Question

What mass must an object have if it has a momentum of 1.5 x 106 kg m/s and a velocity of 60 m/s? ​

Answer 1

Answer:

The mass of the object = m = 25000 kg

Step-by-step explanation:

Given:

• Momentum of an object = 1.5 × 10⁶ kg m/s
• Velocity of an object = 60 m/s

To find:

• A mass of an object.

Solution:

Formula used,

✰ p = mv

Where,

p is the momentum of an object.

m is the mass of an object.

v is the velocity of an object.

Here,

p = 1.5 × 10⁶ kg m/s

m = ? ( we need to find )

v = 60 m/s

Putting the values in the formula, we have:

• 1.5 × 10⁶ = m × 60
• m = 1.5 × 10⁶ ÷ 60
• m = 15 × 10⁶ ÷ 60 × 10
• m = 15 × 10⁶ ÷ 600
• m = 15 × 10⁴ ÷ 6
• m = (15 × 10⁴)/6
• m = 2.5 × 10⁴
• m = (25 × 10⁴)/10
• m = 25 × 10³
• m = 25000 kg
