Question

A student throws a 8 gram of gum horizontal velocity of vo it connects with a mass on the end of 1.6 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 11.6 cm. distance of 3.1 m. When the gum has ross the physics lab from thrown

1) What is initial velocity of the wad of gum? v_max =

2)How long does it take the pendulum (and the gum) to come to rest for the first time? t =
