1. A brick with mass m1=1.6 kg moving to the right with a speed of 4 m/s on a frictionless horizontal surface collides with another brick with mass m2=2.1 kg moving to the left at a speed of 2.5 m/s which is connected to a spring (its spring constant=k), as shown in the figure. After the collision, the brick of mass m1 moves to the right with a speed of 3 m/s.
(1) What is the speed of the brick of mass m2?
(2) What is the compressed distance x of the spring?
