A 1,025.0-kg car pulls a boat on a trailer. The car exerts a 2,075.0-N force on the road and produces an acceleration of 0.5 m/s2. The mass of the boat plus trailer is 700.0 kg. If 80% of the frictional forces are experienced by the boat and trailer, what is the force in the hitch between the car and the trailer

=force × distance a. work b. velocity c. pressure d. momentum

You have a pick-up truck that weighed 4,000 pounds when it was new. you are modifying it to increase its ground clearance. when you are finished

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
