Answer: The red ball has a greater velocity than the purple ball
Step-by-step explanation:
Given the chart :
Ball : Green - - - Red - - - Yellow - - - Purple
Mass : 0.5 - - - - - - 1.2 - - - - - 0.9 - - - - - - 1.7
The four balls have the same momentum
Momentum = mass × velocity
Since momentum is directly proportional to the product of Mass and velocity, and the balls have the same momentum. Therefore the lower the mass of the ball, the higher or greater it's Velocity.
Because if the balls with lower masses have lower Velocities than balls with higher masses, both balls cannot have the same momentum.
Therefore, the only viable option above is, The red ball has a greater velocity than the purple ball, because the red ball has a lower mass than the purple ball
