17. Free Response. A 0.40-kilogram mass is sliding on a horizontal, frictionless air track with a speed of 5.0 meters per
second when it instantaneously hits and sticks to a 2.3-kilogram mass initially at rest on the track. The 2.3-kilogram mass
is connected to one end of a massless spring at the springs unstretched compressed position (equilibrium), which has a
spring constant of 100 newtons per meter. The other end of the spring is fixed to a wall.
Determine the following for the 0.40-kilogram mass immediately before the impact.
į. Its linear momentum
ii. Its kinetic energy
a.
