The two forces shown act in the x-y plane of the T-beam cross section. If it is known that the resultant R of the two forces has a magnitude of 2.9 kN and a line of action that lies 17° above the negative x-axis, determine the magnitude of F1 and the orientation θ of F2.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

+15-35=-20

going in opposite directions

third one with arrows on top of each other going the same direction
