2. On a frictionless air track, a 0.15 kg glider moving at 1.2 m/s to the right collides with and sticks to a stationary 0.25 kg glider. What is the net momentum of this two-glider
system before the collision?

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
