Question

What is the momentum of a train that moves at a speed of 1000 m/s and has a mass of 50kg?

Answer 1

Given ,

Velocity (v) = 1000 m/s

Mass (m) = 50 kg

We know that ,

The product of mass and velocity is called momentum

It is denoted by " P "

$\large\boxed{ \sf{P = mv}}$

The SI unit of momentum is kg.m/s

Thus ,

P = 50 × 1000

P = 50000 kg.m/s

Therefore ,

• The momentum of bullet a train is 50000 kg.m/s

Answer 2

✍ Given ✍

• ✔ Mass Of Train = 50kg.

• ✔ Velocity = 1000m/s.

✍ To Find ✍

• ✔ Momentum Of Train.

✍ Solution ✍

We know the Formula,

$\bf\fbox\red{P\:=MV}$

In this Formula,

P = Momentum,

M = Mass,

V = Velocity.

Put the values.

$\sf\blue{P\:= 1000 \times 50}$

$\sf\pink{P\: = 50000kg.ms}$

So, Your Answer Is 50000kgm/s.
