Please choose the correct answer. Thank you
PLQ-One Dimensional Motion: To measure g with the indlined air track, you place an aluminum spacer under one end of the track to tit it up. Assume you neglect to level the track and iR is tilbed at an angle of 0.09 degrees before you place the spacer at one end. If the length of the air track is 222 cm and the height of the spacer is 2.8 cm, what value of...

please choose the correct answer, thx
One Dimensional Motion: For the acceleration due to a falling weight, what would happen if the hanging weight hit the ground before the cart passed completely through the The cart would stop accelerating at that point and move at a constant velocity, so the measured acceleration would be larger than expected The cart would come to a complete stop and the measured acceleration would be meaningless. The cart would stop accelerating at that point...
