2. Use the conservation of energy to calculate the velocity that the air track glider should have with a hanging mass of 25.0g falling a distance of 50.0 cm. (Hint: Use the formula for kinetic energy K and gravitational potential energy U..) How does this velocity compare with the instantaneous value from the bottom table of the spreadsheet? Assume that your calculated value is the correct value and use percent difference to make the comparison
