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.

Answer the questions below, (Insert the numerical value only, do not use ,+, *, or /) The Relative error for your answer should be less than 0.01, which means if the answer was 50, then the error should not exceed 50*0.01= ±0.5! if the answer was 230, then the error should not exceed 230*0.01= +2 3! if the answer was 2.31467*10^ 3, then you should enter this value: 0.00231467, not this 0.0023 !!!!
