Yashwanth Lagisetty Partners: Christina Wong, Sheldon Shadaia Inclined Planes Purpose The purpose of this lab was to attach a cart to a pulley attached to a weight of a known mass and find the weight of the cart. This was done both with negligible friction, and a trial in which friction was not negligible. Procedure Data Part 1 Measurement Value Average acceleration 0.2532 m/s 2 Angle of Incline 18.20995686° Mass of Hanging weight (M 2 ) 0.44 kg Mass of cart calculated (M 1 ) 1.334079682 kg Mass of cart weighed (M 1 ) 1.3475 kg Part 2 Measurement Value Average acceleration on incline .5551 m/s 2 Average acceleration on flat surface .804 m/s 2 Mass of hanging weight on incline (M 2 ) .75 kg Mass of hanging weight on flat surface (M 3 ) .35 kg Angle of Incline 17.011° Mass of cart calculated (M 1 ) 1.478462811 kg Mass of cart weighed (M 1 ) 1.3575 kg Calculations Part1 Angle of incline Sinθ = 25/80 θ = sin -1 (25cm/80cm) = 18.20995686° Mass of cart m t a = ΣF (m 1 +m 2 )a = (m 2 )(g) – (g • m 1 • sinθ) am 1 + am 2 = (m 2 )(g) – (g • m 1 • sinθ) am 1 + (g • m 1 • sinθ) = (m 2 )(g) –a(m 2 ) m 1 = = 1.334079682 kg Part 2 Formation of formula
