I am confused because on my homework i got marked wrong for this, unless I used to many sig figs.
Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
