(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 1200 kg car moving at 88 km/h collides with a 7600 kg truck moving in the same direction at 65 km/h. The two stick together, continuing in their original direction at 68 km/h. Determine the kinetic energy of the center of mass of the (car + truck) system. Determine the internal energy of the (car + truck) system before the collision. Determine the internal energy of the (car + truck) system after the collision.

2. Relevant equations

m_{1}v_{1}+ m_{2}v_{2}= (m_{1}+ m_{2})v_{f}

Kinetic energy of a system is K = K_{cm}+ K_{int}

K = 1/2mv^{2}

3. The attempt at a solution

88 km/h converted to 24.4444 m/s

65 km/h converted to 18.0556 m/s
