Two marbles of masses M_1 and M_2 (M_1>M_2) are moving under the action of gravity, starting from the same height as shown. The mass M_1 is given an initial velocity in the horizontal direction while M_2 is released from rest.
Which statement is correct? Ignore air resistance. (Check all that apply)
Please explain the rationale behind your answer.
Your answer
Suppose you could not IGNORE air resistance, how would this effect the results of the experiment?
