Question

6. Analysis/Report 1. Final velocity as a function of the mass: Mass of the glider is m = 210 g. To calculate final velocity using this formula: m, ' 011 + m2. V2.1 = (mı + m) • vf (5) a) Using DATA Table 2 to record your results and complete the table below table and calculate errors.( Error % Added load mile) Added load m2(e) Vii(m/s) Vi2(m/s) vy(m/s) measured of(m/s) calculated \Vgsm-Val x 100 Vic 0 0 0 0.245 0.231 6% 100 0 0 0.327 0.282 15% 140 40 o 0.268 0.239 12% 140 100 0 0.175 0.199 12% 100 140 0 0.134 0.136 1.74% 40 140 0 0.201 0.225 10.6% 0 100 0 0.125 0.263 18.2% Table 1

Which effect has increasing of mass on initial and final velocity of the gliders?

DATA TO USE

Answer 1

By m Momentum conservation Equation movi + m. Ut (m, + m2): 431-0 + Vp m, vit me uri m, tma Effects if (1994m2) is then I final / velocity decresing And if m₂ =0 as mentioned in table) then Ug = m . vito Increasing m, to then [ug = Vi re (final velocity initial whity if m is decresing then to maintain conservation of momenturn egr D. Hence Usi increasing bif(m, m2) is deerning then vf Binal velocity) is increasing
