Answer: $v=-\frac{11}{3} m/s \left$

Explanation:

Given

Mass of car A $\left ( m_a\right )=1 kg$

Mass of car B $\left ( m_b\right )=2 kg$

velocity of cart A=3 m/s

velocity of cart B=-7 m/s

Conserving momentum

$m_au_a+m_bu_b=\left ( m_a+m_b\right )v$

$v=\frac{m_au_a+m_bu_b}{\left ( m_a+m_b\right )}$

$v=-\frac{11}{3} m/s \left ( i.e. in\ left\right )$

A 2.00 kg steel gas can holds 25.0 L of gasoline when full. What is the average density (in kg/m3) of the full gas can, taking i

ddd [48]

Answer:80kg/m^3

Explanation:

1L = 0.001m^3

25L= 25 *0.001 = 0.025m^3

Average density =mass/volume

Average density =2/0.025=80kg/m^3
