Question

A bus weighing 900 kg is at rest on the bus stands.
What is linear momenyum of bus?

Answer 1

Given :

A bus weighing 900 kg is at rest on the bus stands

To Find :

Linear momentum of the bus

Solution :

Linear momentum is defined as product of mass and velocity

$\bigstar\ \; \underbrace{\sf P=mv}$

Mass , m = 900 kg

As the bus is in rest , So

Velocity , v = 0 m/s

$:\implies \sf P=mv\\\\:\implies \sf P=(900)(0)\\\\:\implies \sf P=0\ kg.m/s\ \; \bigstar$

Linear momentum of the bus = 0 kg.m/s

More Info :

• SI unit of momentum is Kg.m/s
• SI unit of mass is Kg
• SI unit of velocity is m/s

Answer 2

Answer:

⇒Linear momentum of bus is 0 kg. m/s.

Explanation:

Given that,

• Mass (m) = 900 kg
• Velocity (v) = 0 m/s

As we know that,

The product of the mass and the velocity called " Linear momentum " .

$\sf \:{ \underbrace{ \red{p = m \times v}}}$

[ Putting values ]

$\implies \sf \: p = 900 \: \times \: 0 \: kg. \: m/s \\ \\ \implies \sf \: {\underbrace{\green{ p = 0 \: kg.m/s}}}$
