Q. A simple pendulum has a length of 2.20 m and is pulled a distance y = 0.17 m to one side and then released. (Assume small angle.)

What is the speed of the pendulum when it passes through the lowest point on its trajectory?

Q. A hot iron horseshoe (mass = 0.50- kg) which has just been forged, is dropped into 1.45 -L of water in a 0.50 kg iron pot at first at 22oC. If the final equilibrium temperature is 32oC, calculate the initial temperature of the hot horseshoe (in Celsius).
