A dog of mass 10 kg sits on a skateboard of mass 2 kg that is initially traveling south at 2 m/s. The dog jumps off with a veloc

inna [3103]

Answer:

17 m/s south

Explanation:

$m_1$ Mass of the dog = 10 kg

$m_2$ Mass of skateboard = 2 kg

v = Combined velocity = 2 m/s

$u_1$ Velocity of the dog = 1 m/s

$u_2$ Velocity of skateboard

In this scenario, linear momentum is conserved

$(m_1+m_2)v+m_1u_1+m_2u_2=0\\\Rightarrow u_2=-\dfrac{(m_1+m_2)v+m_1u_1}{m_2}\\\Rightarrow u_2=-\dfrac{(10+2)2+10\times 1}{2}\\\Rightarrow u_2=-17\ m/s$

The speed of the skateboard post-dog jump will be 17 m/s south, considering north as the positive direction
