Question

a bus of mass 5000 kg is moving with a velocity of 60km/h. find is momentum.

Answer 1

Answer:

Explanation:

Momentum = mass * Velocity

Here

mass = 5000 Kg

and velocity = 60Km/h = 60/3.6 m/s = 16.67m/s

momentum = 5000 * 16.67

                   = 83333.33 Ns

                   = 83.33 KNs

Answer 2

$\large{\bold{\underline{To \:Find}}}$

Momentum of the body.

I.e. ${Momentum (p)}$ = ?.

$\large{\bold{\underline{\underline{Step - by -Step - Explanation}}}}$

It's given

• m = 5000 kg.
• v = 60 km/h

As velocity is given in km/h it needs to be converted to m/s.

${v = 60 \: Km/h = 60 \times 5/18}$

${v = 16.67 \: m/s}$

Now,applying momentum formula.

$\huge{\boxed{\boxed{p = mv}}}$

${p = 5000 \times 16.67}$

${p = 83,350 \: kg m/s}$

$\huge{\boxed{\boxed{p = 83,350 kgm/s}}}$

So, the momentum of the bus is 83,300 kgm/s.
