    No more info, got the answer 75,7W now :rolleyes:

    So change in KE + change in PE? PE=mg(hf-hi) where hf-hi= s sin 10

    So I need to divide the change in kinetic energy by the time? KE=(1/2)mv^2 where m is the mass (1200kg) and v is the speed (25 and 8,3 m/s)? am I completely lost?

    Now I’m just confused. How do I calculate the W then? and where do I apply the forces

    I don’t get how this changes my calculations

    a=((25-8,3)/8)=2,1 m/s^2 Fg=1200(9,8)sin10=2042,1N Fa=ma+Fg Fa=1200(2,1)+2042,1=4562,1N P=Fa v P=Fa ((Vo+Vf)/2) =75958,965 W =102hp

    So my result is 102hp, but it’s not correct.
