What is the momentum
of an 800-kg car
| traveling at a velocity
of 10 m/s? what is its
momentum if it speeds
up to 50 m/s?

P = 8000 Kg m/s

When speed is increased to 50 m/s,

P = 40,000 kg. m/s

Explanation:

Given data:

Mass = 800 Kg

Velocity = 10 m/s

Momentum = ?

Speed increased = 50 m/s

Momentum = ?

Solution:

Formula:

P = mv

P = 800 kg× 10 m/s

P = 8000 Kg m/s

When speed is increased to 50 m/s.

P = mv

P = 800 kg× 50 m/s

P = 40,000 kg. m/s

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
