A900-kg car traveling east at 15.0 m/s suddenly collides with a 750-kg car traveling north at 20.0 m/s. the cars stick together after the collision. in what direction does the wreckage move just after the collision?

The wreckage moves in the direction 48° N of E just after the collision

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

Given:

mass of car 1 = m₁ = 900 kg

initial velocity of car 1 = u₁ = 15 i m/s

mass of car 2 = m₂ = 750 kg

initial velocity of car 2 = u₂ = 20 j m/s

Asked:

final velocity = v = ?

Solution:

Firstly , we will use Conservation of Momentum Law as follows:

Next , we could find the direction of this final velocity as follows:
