This one the last questions on my mechanics paper, its hard to visualize without drawing a diagram i found, but i still cant solve it(adsbygoogle = window.adsbygoogle || []).push({});

1.

A tractor of 6000kg approaches a slope at arcsin(0.05) to the horizontal. The non-gravitational resistance to motion on this slope is 2000N. The tractor accellorates uniformly from 3m/s to 3.25m/s over a distance of 100m while climbing the slope

1. Calculate the time taken to travel this distance of 100m, and the average power required over this time period.

2. Relevant equations

p = Fv

p= F/t

f = ma

Work Done = 0.5mv^2

3. The attempt at a solution

i got as far as using s = (u+v)/2 x t, which gives the time as 32 seconds. i'm just not sure how to find the average power because i dont know where to put the 2000N resistance in the equation, plus the angle of the slope confuses the issue somewhat
