I was not entirely sure, but I assumed saying the collision is 'frontal' was an implication the collision is central, though I have not tried solving this as an offset collision. I assumed the latter:
It could be the book, since the solution states delta energy to be only 24.3 J, a weirdly...
Hi,
I assumed I was supposed to find the amount of kinetic energy body 2 receives after contact, assuming the collision is central, body 1 will be at rest after the collision.
I started by using the equation for conservation of momentum:
\begin{align}
m_1v_1 = m_1v_1' + m_2v_2' \\
50 * 20 =...
