Urgent!!! A bowling ball dispenser takes 15 seconds to raise a 5 kg ball by 0.4 m, releasing it at some speed. If the power consumption of the dispenser is 10 W, what speed is the ball released at?

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.
