What are the answers to these questions

To satisfy the objectives do the following steps. Open the following link to collect your data. WWW 1 Change the angle {8) between the ramp and the horizontal level, and record it 19.1%?!th below. Ream the height (y) of the tamain table below. Choose your object from the list of objects provided on phet simulation the ramp sim; select the friction surface option to keep the object at rest at the selected position on the ramp. Control the distance that will be travelled along the ramp by the object using the position controller X =15m. Once you ll-$93. (X), check on. frictionless check square to allow the object to slides down the ramp from zero initial velocity. At the end of the ramp read the velocity from the velocity meter displayed on the sim window. Record the measurements as shown in the table below. Calculate the time needed for the sliding object to travel the distance it along the ramp using the following equation: t} +0 X = ( \"2 ')t 9 Repeat steps 5 to 10 and ll you data in the table below. We; 1- Use excel soware to draw a graph between X Vs t2 2- Perform a linear best t to the data of X versus t2. with t2 as the abscissa (X-axis) and X as the ordinate {Y-axis). 3- The slope of this t should be equal to {afZ} where a is the glider's acceleration. 4- Calculate the gravity 3 where MN WQONUU-h- _ a g- stn -m 9-17.39 Sin 9-0.2989 m Calculate tlle percent difference for the value of gravity you found (the experimental value) The actual value is 9.8 mIsAZ, % Difference = {experimental actual);Ir actual x 100%
