A student throws a 9 gram of gum is thrown across the physics lab from a distance of 2.6 m. When the gum has a horizontal velocity of v0 it connects with a mass on the end of 1.47 kg simple pendulum which is initially at rest. The pendulum has a length of L of 0.88 m. The gum sticks to the pendulum mass and swings backwards to gain a vertical height of 12.3 cm.
1)
What is initial velocity of the wad of gum?
vmax =
m/sec
2)
How long does it take the pendulum (and the gum) to come to rest for the first time?
t =
seconds
