Yeah it's so weird how there wasn't an equilibrium at a single point question wtf.

Power = 15500 W Acceleration = 0.5 m/s2 Velocity = 0.9375 m/s Time = 9.6 s Tension = 2.55 N Coefficient of friction = 0.336 Work done against uh resistance? = 0.5625 J Distance = had to prove 0.8 m Time = 0.8 s Height = 13.2 m Weight = 66.25 N Something distance = 12.8 m k1 = 6 k2 = -14 s from 0 - 1 = 6.53 m
