Is this a SCIENCE question?
Is the ball PULLED?
1.5 WHAT above ITS lowest point?

the potential energy at the high point is equal to the kinetic energy at the low point
m g h = 1/2 m v^2 ... v = √(2 g h)
the mass is in kilograms , so the height is probably in meters
v = √(2 * 9.8 * 1.5) m/s
m g h = 1/2 m v^2 ... v = √(2 g h)
the mass is in kilograms , so the height is probably in meters
v = √(2 * 9.8 * 1.5) m/s
