Assume mechanical energy is conserved. 18.9 m/s O 0.463 m/s O 14.6 m/s O 7.32 m/sQuestion 2 Ball a Ball c Ball b In the figure provided, three balls of equal masses are released from the same position. If they are released with equal speeds, which ball has the slowest speed when it hits the ground? O Ball bhas the slowest speed. Ball chas the slowest speed. They all have the same speed. O Ball a has the slowest speed
