A small steel ball bearing with a mass of 15 g is on a short compressed spring. When aimed vertically and suddenly released, the spring sends the bearing to a height of 1.37 m. Calculate the speed at which the ball leaves the spring.
Calculate the horizontal distance the ball will travel if the same spring is aimed 38° from the horizontal.
