Recall that rolling resistance is a force experienced by a vehicle and is given by F=cmg where m is the mass of the vehicle and contents, cis the rolling resistance coefficient, and g = 9.8 m/s² is acceleration due to gravity. Suppose you are driving a large truck of mass 2500 kg with c = 0.02 to go and pick up some heavy items totaling 300 kg that are located at a warehouse. You are evaluating two different routes to take: route A is 30 km to the warehouse and 35 km back to your house; route B is 35 km to the warehouse and 30 km back to your house. Considering the amount of work (and therefore the amount of fuel) required to overcome rolling resistance, which is the better route?

Displayed to the right are two carts connected by a cord that passes over a small frictionless pulley. Each cart rolls freely with negligible friction. Consider the mass of the cart to be m1 = 18.1 kg and the angle the first cart sits on to be θ1 = 37.5°, while the mass of the second cart as m2 = 24.1 kg and the angle it sits on to be θ2 = 50.5°.a = 1.759m/s^2 What is the equation for tension in regards to the rope coming from the second block? Answer in terms of the mass of the block m2, the acceleration due to gravity g, the angle θ2, and the acceleration of the blocks found previously a. Calculate the tension in the rope T in newtons.

There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For F1 = 15.7 N, a = 14.7 m/s2, and θ = 34.1°, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction. (State the direction as a negative angle measured from the +x direction.)
A 70-kg bicyclist is riding her 15-kg bicycle downhill on a road with a slope of 8° without pedaling or braking. The bicyclist has a frontal area of 0.45 m2 and a drag coefficient of 1.1 in the upright position, and a frontal area of 0.4 m2 and a drag coefficient of 0.9 in the racing position. Disregarding the rolling resistance and friction at the bearings, determine the terminal velocity of the bicyclist for both positions. Take the air density to be 1.25 kg/m3.
Two masses mA =9.3kg and mB=6.1kg are on inclines and are connected together by a string as shown in the figure. The angles theta subscript A=700 and theta subscript B = 360 . In the absence of the friction, the force F is required to pull the masses at a constant velocity up the fixed inclines. The force F is now removed. What is the magnitude of the acceleration of the two blocks? Take g =9.81 m/s2, and express your answer using two decimal places.

Two masses with mass mA = 3.220 kg and mB = 22.81 kg, respectively, hang with a massless line over an inhomogeneous pulley with mass mC = 41.81 kg. The mass center of the pulley is located in the middle of the pulley. The pulley is attached with a frictionless bearing in the middle. g = 9,806 m / s². If mass A accelerates upwards by 5.75 m/s², what force then acts on the suspension of the inhomogeneous pulley?
