Asked by Ebieride
A 1200kg travelling east collides with another 1000kg car travelling north. If they are both travelling at 90km/h and the collision is completely inelastic, find the velocity of the systemafter collision.

the final mass is 2200 Kg if it is totally inelastic and they stick to each other.
east momentum
1200 * 90 = 2200 Ve
north momentum
1000 * 90 = 2200 Vn
|V| = sqrt (Ve^2+Vn^2)
tan compass angle east of north = Ve/Vn
east momentum
1200 * 90 = 2200 Ve
north momentum
1000 * 90 = 2200 Vn
|V| = sqrt (Ve^2+Vn^2)
