Response Details:
Mass of the wagon, M = 40 kg
Angle made with horizontal, θ = 17.5o
Tension in the rope, F = 140 N
Distance moved along the hill, S = 76 m
Initial velocity, U = 0 m/s
Net Force , Fnet = F - M g Sin θ
= 140 - ( 40 * 9.8 * 0.301 )
= 22.12 N
Acceleration, a = Fnet / M
= 22.12 / 40
= 0.553 m/s^2
V2 - U2 = 2 a S
V2 - 0 = 2 * 0.553 * 76
Final velocity, V = 9.17 m/s
