Question

When Marissa uses Marble B instead of Marble A, the only difference is the mass of the marble. If Marble B has a greater mass compared to Marble A, it will experience a greater force when Marissa releases the slingshot, assuming the same force is applied. Therefore, Marble B may travel farther than Marble A did in the previous launch because of its greater mass. rephrase like a 9th grader shorten

Answer 1

If Marissa uses Marble B instead of Marble A, the only difference is the weight of the marbles. If Marble B weighs more than Marble A, it will be pushed harder when Marissa lets go of the slingshot, as long as she uses the same force. So, Marble B could go further than Marble A did before because it weighs more.
