# Problem 8-75 Inelastic collision - Part 2 - B

Two trucks have a completely inelastic collision. After the collision, they have a common velocity of $11 \;m/s$ at $35^\circ$ south of west. Before the collision, one truck $(\text{mass} \; 2.3\times10^4\; kg)$ has a velocity of $15\; m/s$ at $51^\circ$ south of west. Determine the initial velocity (magnitude and direction) of the other truck $(\text{mass} \; 1.2\times10^4\; kg).$

Accumulated Solution

Correct.

The problem is described in a NSEW system so above is a sketch of the situation just before the collision. Also we have chosen x and y as East and North which is the most common choice.

What is a reasonable sketch of the situation after the collision?

(A)

(B)
