(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I could really do with some feedback here. I've tried a solution but I'm unsure about the answers i got, especially in the second part.

2. Relevant equations

P = µFx = Max ∑MB = ∑Mad

V = U + at

3. The attempt at a solution

Taking X in the horizontal direction and Y in the vertical. µ = Friction factor d = distance vertically to G a= acceleration.

Force P = µFx = Max ∑MB = ∑Mad = 30(9.81)x(0.2)=30a(0.2)

58.86=6a

a=9.81 m/s2

µFx = Max 0.5Fx = 30(9.81) Fx = 590N

V after 5 sec: V = U + at = 0 + (9.81)5 V=49.05 ????? - seems too fast!
