What is the momentum of a bullet of mass 20g?

What is the momentum of a bullet of mass 20g?

The momentum of a bullet of mass 20 g fired from a gun is 10 kg m/s.

What is the formula for the momentum of a bullet?

Hint: Here we have been given with mass of the object, its initial and final velocities. The momentum of the body (bullet) can be calculated using the formula of momentum: \$p=mv\$.

What is the momentum of a 75g bullet?

the momentum of a 75 g bullet is 9 kg⋅m⋅s−1 toward a target.

What is the real formula for momentum?

p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.

What is the final momentum of the bullet?

Thus momentum of the bullet P=mv=0.025×100=2.5 kg m/s.

What is the total momentum of a bullet?

The total momentum of the bullet and the gun before firing would be zero because velocities of both of them will be zero. Was this answer helpful?

Which is having higher momentum a bullet of mass 10g?

Solution: A bullet of mass 10 g moving with the velocity of 400 m/s and a cricket ball of mass 400 g thrown with the speed of 90 km/h . Then the cricket ball has higher momentum.

Why is the momentum of bullet very high?

Answer and Explanation: The term inertia is a property of mass while the linear momentum is directly proportional to the mass and the velocity of the moving body. Since the velocity of the fired bullet is greater, therefore its momentum is also greater.

What is SI unit of momentum?

Momentum
SI unit kilogram meter per second (kg⋅m/s)
Common symbols p, p
Other units slug⋅ft/s
Dimension MLT1

What is P in physics?

p = momentum m = mass v = velocity The definition of momentum. It is conserved (constant) if there are no external forces on a system.

What is the SI unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

What is the momentum of bullet of mass 0.02 kg?

(b) a bullet of mass 0.02 kg moving at 400 m/s. Therefore, the momentum of the elephant is 10000 kg−m/s 10000 k g − m / s . Therefore, the momentum of the bullet is 8 kg−m/s 8 k g − m / s .
