The speed of the ball released is 7.75 m/s.
Speed of the ball
The speed of the can be determined from the principle of conservation of energy as shown below;
supplied energy of the dispenser = kinetic energy of the ball
Power x time = kinetic energy of the ball
10 x 15 = ¹/₂ x 5 x v²
150 = 2.5v²
v² = 150/2.5
v² = 60
v = √60
v = 7.75 m/s
Thus, the speed of the ball released is 7.75 m/s.
