Question #b14aa

Answer 1

This is known as a perfectly inelastic collision

Explanation:

In a perfectly inelastic collision, `m_1v_1+m_2v_2=(m_1+m_2)v'`

Meaning that once they stick together, the new mass is the sum of the individual initial masses. Momentum is always conserved. Kinetic Energy is never conserved.

In this problem:

`0.5kg*10m/s+1kg*0m/s=(0.5kg+1kg)v'`

So, 5Ns=1.5kg*v'

v'= `frac{5Ns}{1.5kg}`

You can finish the problem. The answer will be in m/s
