Question
Reminder: Speed is the magnitude of the velocity vector.In procedure 3: assume cart 1 has mass 270 g and cart 2 has mass 299 g. Assume the track is frictionless, and the initial speed of cart 1 is 2.02 m/s. Find:
- v1, the speed of cart 1 after the collision 1 m/s
- v2, the speed of cart 2 after the collision 2 m/s Reminder: Speed is the magnitude of the velocity vector.

Explanation / Answer
(1/2)*m1*u1^2=(1/2)*m2*v2^2.......
V2=sqrt[(m1/m2)]*u1=1.919m/sec......
V1=0
