got it, thanks!
Could you also help me with this one?
Two 2.0 kg masses, A and B, collide. The velocities before the collision are vA = 20i + 25j and vB = -15i + 10.0j. After the collision, v'A = -3.0i + 18j. All speeds are given in meters per second.

A block of mass m1 = 1.8 kg slides along a frictionless table with a speed of 10 m/s. Directly in front of it, and moving in the same direction, is a block of mass m2 = 4.4 kg moving at 2.8 m/s. A massless spring with spring constant k = 1160 N/m is attached to the near side of m2, as shown in...
1. In Fig. 10-41, ball 1 with an initial speed of 12 m/s collides elastically with stationary balls 2 and 3 that are initially in contact with each other. The centers of balls 2 and 3 are on a line perpendicular to the initial velocity of ball 1. The three balls are identical. Ball 1 is aimed...
