Answer:
<em>a) Fvt cosθ</em>
<em>b) Fv cosθ</em>
<em></em>
Explanation:
Each horse exerts a force = F
the rope is inclined at an angle = θ
speed of each horse = v
a) In time t, the distance traveled d = speed x time
i.e d = v x t = vt
also, the resultant force = F cosθ
Work done W = force x distance
W = F cosθ x vt = <em>Fvt cosθ</em>
<em></em>
b) Power provided by the horse P = force x speed
P = F cosθ x v
P = <em>Fv cosθ</em>
The one that is loaded worst. The overall weight is not important; tongue weight is a matter of loading. Our 12,000 lb snow cat trailer, which has stops to position the cat properly, has under 100 lbs tongue weight. Excessive tongue weight is a Bad Thing because it reduces weight on the towing vehicle's front wheels, leading to instability.
C I believe is the correct answer. Developing possible solutions would be easier than spending hours researching or identifying the need.
B. The object stops from a velocity of 12.0 m/s
