Charlie is playing with his daughter Toney in the snow. She sits on a sled and asks him to slide her across a flat, horizontal field. Charlie has a choice of (a) pushing her from behind by applying a force downward on her shoulders at 30° below the horizontal (Fig. 5.18a) or (b) attaching a rope to the front of the sled and pulling with a force at 30° above the horizontal (Fig. 5.18b). Which would be easier for him and why?

An eagle descends steeply onto its prey. Its weight (the gravitational force on the eagle), of magnitude 60.0 N, points downward in the -y-direction. The lift force exerted on the eagle’s wings by the air, also of magnitude 60.0 N, is at an angle of 20.0° from the vertical (the +y-direction) and 70.0° from the +x-direction. The drag force (air resistance) exerted on the eagle by the air has magnitude 15.0 N and is at an angle of 20.0° from the-x-direction and 70.0° from the +y-direction. Find the x- and y-components of the net external force on the eagle, and find the force’s magnitude and direction.
A trunk with a weight of 250N is at rest on a floor. The coefficients of friction between the trunk and
floor are H=0.200 and Ps=0.350.
a) What is the largest horizontal force that can be applied to the trunk for which the trunk will not move?
(Any force larger than this will start the trunk moving).
b) Once the trunk is moving, what horizontal force is required to keep the trunk moving with a
constant speed?
