If a tennis ball has a velocity of 18 m/s and a momentum of 1.06 kg. m/s, what is the mass of the tennis ball in grams?
Round the answer to two significant figures.
Blank grams

Respuesta :

Answer:

The mass of a tennis ball is 59 grams.

Explanation:

Given that the formula for momentum is p = m×v where m represents mass (kg) and v is speed (m/s). Then, you have to substitute the values :

[tex]p = m \times v[/tex]

[tex]let \: p = 1.06,v = 18[/tex]

[tex]1.06 = m \times 18[/tex]

[tex]1.06 \div 18 = m[/tex]

[tex]m = 0.0589kg \: (3sf)[/tex]

[tex]m = 0.0589kg \times 1000[/tex]

[tex]m = 59g \: (3sf)[/tex]

Answer:

59g
