A ball, of mass 0.3Kg, is held on the inside of a smooth hemispherical bowl at a height 0.15 m above the base. It is then released. Assuming there is no friction, the acceleration due to gravity, g, is 10 m/s2 and the potential energy is zero at the base of the bowl - What is the maximum value of speed that the ball reaches?

What's with the name changes? Are you triplets? Use conservation of energy.
When they say the surface is "smooth" they perhaps want you to assume the ball does not roll.
