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.
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?
