A student throws a 9 gram of gum is thrown across the physics lab from a distance of 2.5 m. When the gum has a horizontal velocity of vo it connects with a mass on the end of 1.62 kg simple pendulum which is initially at rest. The pendulum has a length of L of 0.74 m. The gum sticks to the pendulum mass and swings backwards to gain a vertical height of 12.7 cm.

(a) What is initial velocity of the wad of gum?

vmax = ?

i used the formula 2pi (l/g)squareroot then 2pi/T to get the w and timed it by Amp but i still didn't get it right
