Question

4. A truck of 1000 kg mass is moving 1 point
with a velocity of 0.5 m/s. What is its
momentum ?
500 g m/s
O 50 Kg m/s
O 5000 Kg m/s
O 500 Kg m/s​

Answer 1

Answer:

500 kg m/s

Explanation:

Given : m=1000 kg v=0.5 m/s

∴ Momentum of the car P=mv=1000×0.5=500 kg m/s

if this help you pse follow me

Answer 2

Solution :-

Given ,

• Mass of truck = 1000kg
• Velocity of truck = 0.5 m/s

We need to find ,

• Momentum of truck = ?

As we know that ,

p = m × v

Where ,

• p → momentum = ?
• m → mass of truck = 1000 kg
• v → velocity of truck = 0.5 m/s

Substituting the values we have ,

⇒ p = 1000 × 0.5

⇒ p = 1000 × 1/2

⇒ Momentum ( p ) = 500 kgm/s

Hence , momentum of truck is 500 kgm/s . So , option D is your answer .

• p = m × v
• F = m × a
• a = ∆v/t
• v = u + at
• S = ut + 1/2 at²
• v² - u² = 2as
• v² = - 2gH
